A small lemon wedge rests on the plate beside the toasts. A small clear glass jar of capers, a folded striped cream-and-blue linen tea towel, and a small bunch of fresh dill sit on the marble beside the plate. Soft midday light from the kitchen window.

This is the lunch I make when I want something that eats like a real meal but doesn't ask anything of my Tuesday afternoon. Tuna salad with cottage cheese folded in instead of mayo, brightened with lemon, dill, capers, and a crack of black pepper, then piled high on a slice of grilled dark rye. The whole thing comes together in ten minutes and quietly clears 35 grams of protein.

The cottage cheese is what makes this work. It does what mayo does (binds, makes everything creamy) but without the heaviness, and it brings its own backbone of protein and tang. The grilled rye is non-negotiable. A piece of bread that's been kissed by a cast iron pan is the difference between a sad desk lunch and something I actually look forward to.

Why this one earns a weeknight

What you'll love about it

  • 01Thirty-five grams of protein per serving without thinking about it. Two cans of tuna and a generous scoop of cottage cheese do the heavy lifting.
  • 02Cottage cheese instead of mayo is the small swap that changes the dish. Lighter, brighter, tangier, and you don't end up needing a nap afterwards.
  • 03Ten minutes start to finish, mostly because the only thing that touches heat is the bread. The salad itself is a fold-together job.
  • 04The grilled rye is the move. A slice of bread kissed by a cast iron pan turns desk lunch into something worth looking up from.
A near-overhead view of a pair of hands in a beige Breton-striped tee gently folding the cottage cheese tuna salad together in a large cream-speckled stoneware mixing bowl with a wooden spatula. Visible inside the bowl: flakes of tuna, white cottage cheese curds, scattered bright green capers, finely chopped fresh dill, thin slices of red onion, a small dollop of dijon mustard half-stirred in. Two empty drained tuna cans, a small dish of chopped dill, a halved juiced lemon, a small jar of capers, and an open tub of cottage cheese with a spoon resting in it surround the bowl on the white marble counter.
Fold gently. The texture is the whole point: distinct tuna flakes and cottage cheese curds, not a smooth paste.
Ingredients

For the tuna salad

  • 2 (5 oz)cans good-quality tuna, drained well, packed in olive oil if you can find it
  • ¾ cupfull-fat (4%) cottage cheese
  • 1 Tbspdijon mustard

  • a generous pinchblack pepper

For the grilled rye

  • 2thick slices of good dark rye or pumpernickel bread, about ½ inch thick
  • 1 Tbspolive oil
  • 1 Tbspunsalted butter

To serve

  • lemon wedges
  • more chopped fresh dill
  • flaky sea salt and cracked black pepper
Method

How I make it

  1. 01
    Mix the tuna salad.
    In a medium bowl, flake the drained tuna with a fork into rough chunks (not too fine; the texture is good). Add the cottage cheese, dijon, lemon juice, capers, chopped dill and chives, sliced red onion, salt, and a generous pinch of black pepper. Fold gently with a spatula until everything is combined but you can still see the tuna flakes and the cottage cheese curds. Taste; adjust salt, lemon, or pepper.
  2. 02
    Grill the bread.
    Heat a cast iron skillet or grill pan over medium heat until hot. Brush both sides of the rye slices lightly with olive oil. Place in the dry pan and grill 2 to 3 minutes per side, until deeply golden with charred edges. Move the toasts to plates and slather the warm tops with the softened butter while they're still hot.
  3. 03
    Assemble and serve.
    Pile a generous mound of the cottage cheese tuna salad onto each warm slice of grilled rye, letting it spill slightly over the edges (this is the whole appeal). Scatter a few more capers on top, a fresh dill sprig, a tiny pinch of flaky salt, and a crack of black pepper. Serve immediately with a lemon wedge on the side.

The salad on the spoon shows visible tuna flakes and cottage cheese curds. A cream-speckled mixing bowl with the remaining salad sits at the upper-left edge, a small clear glass jar of capers at the lower-left, a lemon wedge on the plate, and a folded striped cream-and-blue linen tea towel at the lower-right, on a white marble counter.
    Pile it high. The salad mounding slightly over the edge of the toast is the whole appeal.

A lemon wedge and a small clear glass jar of capers sit softly behind.
A note from Anna

Full-fat (4%) cottage cheese is doing the work here. The low-fat stuff is too watery; it makes the salad runny instead of creamy. Drain the cottage cheese briefly through a fine-mesh sieve if your tub has a lot of liquid pooled at the top. And rinse the red onion under cold water before adding; it takes the sharp bite off so it tastes like onion without screaming at you. If you can find tuna packed in olive oil (Italian or Spanish brands are great), it's noticeably better here than water-packed.

What to serve with it

Round out the table.

  • ·01
    A pile of cucumber rounds and crisp radishes
    Cut into thin coins, scattered with a tiny pinch of flaky salt. The crunch balances the creamy salad.
  • ·02
    A handful of arugula or watercress
    Dressed simply with olive oil and lemon, piled beside the toast.
  • ·03
    Cold sparkling water with cucumber
    Or a small glass of crisp white if it's a Friday.
Storage & reheating

Keeping the leftovers good.

Fridge: The tuna salad keeps for 3 days in a sealed container in the fridge. The grilled rye is best the day of; toast fresh slices each time you eat it.

Reheat: The salad is best cold from the fridge or at room temperature. Re-toast a fresh slice of rye in a dry pan for a minute when you're ready to eat.

Make ahead: Make the full batch of salad on Sunday; it gets along well in a sealed container through Wednesday. Toast a slice of rye fresh each day.
