Tuna Salad Sandwich with Pickles & Apple
Flake a can of tuna, toss it with diced apple and pickles, and dress the whole thing with yogurt and a splash of pickle brine. Ten minutes, no cooking, and you’re sitting on 48 grams of protein with just 3 grams of fat.
The yogurt-and-brine swap does what mayo never could: it keeps the tang and the creaminess while stripping the fat down to almost nothing. That ratio is not a rounding trick. Tuna packed in water plus nonfat yogurt plus zero oil means this entire sandwich carries less fat than a single tablespoon of olive oil.
Twenty-four randomized trials found that keeping protein high during a caloric deficit changed what the body burned — more fat lost, more muscle preserved. This sandwich covers nearly half that daily protein threshold in one meal, for fewer calories than most people spend on a snack.
Ingredients
- red onion 0.25
- pickles 4
- apple 1
- tuna, in water 5 oz
- yogurt, nonfat 2.5 fl oz
- bread, whole wheat 2 slices
- cherry tomatoes 5
Method
-
Finely chop the onion. Dice the pickles and apple into small cubes.
-
Flake the tuna with a fork in a bowl. Mix the tuna with the onion, pickles and apple.
-
In a small bowl, whisk together a dressing of yogurt and some pickle brine, seasoned with salt and pepper to taste.
-
Combine the tuna salad with the dressing. Add more pepper and salt if desired.
-
Serve the tuna salad on the bread. Place the tomatoes alongside.
Toast the bread for a crunchier contrast against the cold salad. Taking this to go? Scoop the tuna salad and tomatoes into a sealable container and pack the bread separately. The bread stays intact and the salad stays cold.
This sandwich delivers 48 grams of protein at 451 calories, covering roughly half the daily protein threshold (about 1.2 g/kg) that 24 randomized trials linked to better fat loss and muscle preservation during a caloric deficit. The extreme leanness comes from two specific choices: tuna packed in water instead of oil, and nonfat yogurt with pickle brine instead of mayo.
Protein & Body Composition During a Deficit — 24 Randomized TrialsBehind this recipe
Does all 48 grams of protein from this sandwich actually get used?
Yes. The widely repeated 30-gram ceiling was never real. It came from experiments that stopped tracking too soon. When researchers used isotope tracers to follow amino acids for 12 straight hours, they watched the body channeling protein toward muscle from a 100-gram dose, well past the point older studies had given up measuring. Forty-eight grams from this sandwich is comfortably within range.
Read the full evidence reviewHow does this sandwich have only 3 grams of fat?
Two moves. The tuna is canned in water, not oil, and the dressing uses nonfat yogurt with pickle brine instead of mayo. A single tablespoon of mayo alone carries about 10 grams of fat. Swap it out and the entire sandwich drops to 3 grams without losing the creamy, tangy texture the salad needs.
Does the fiber in this sandwich actually help with fat loss?
Apple and whole wheat bread together deliver 9 grams of fiber here. Apple contains pectin, a viscous fiber, which is the specific type that 62 pooled clinical trials linked to modest body weight reduction. Nine grams from a single meal covers roughly a quarter of the daily target, and viscous fiber appears to work partly through slowing digestion and extending the feeling of fullness.

The tuna salad keeps well in a sealed container in the fridge for up to a day. Keep the bread separate until you eat. The apple won’t brown much since the pickle brine’s acidity slows oxidation.
