This is a canned tuna salad bound with plain Greek yogurt, Dijon mustard, and lemon juice instead of mayonnaise โ no cooking required, ready in five minutes. At 45 calories and 6 grams of protein per serving, itโs a genuinely light lunch that doesnโt taste like a compromise. The capers and mustard do the heavy lifting on flavor, so youโre not just eating sad diet food.
What makes this version work
Two things matter here. First, the draining step โ mixing everything and then letting it sit in a colander lined with paper towels pulls out the excess water from both the tuna and the yogurt, which means the finished salad is thick and scoopable rather than watery and loose. Skip it and youโll have a puddle on your cracker. Second, the combination of capers, Dijon, and lemon juice gives you salt, tang, and brightness from three different angles, so the yogurt base never tastes flat. Greek yogurt has enough fat and protein to cling to the tuna the way mayo does โ plain regular yogurt is too thin and will separate.
Troubleshooting
- Salad tastes bland after draining: Draining removes some of the seasoning along with the water. Taste after draining and add a pinch of salt, an extra squeeze of lemon, or a few more capers before serving.
- Yogurt flavor is too sharp or sour: Full-fat Greek yogurt is noticeably milder than non-fat. If all you have is non-fat, add a small drizzle of olive oil to round it out.
- Capers are too salty or overpowering: Give them a quick rinse under cold water before adding. Brine-packed capers are saltier than water-packed ones โ the recipe calls for water-packed, so check the jar.
- Mixture is still too wet after draining: Press the paper towels gently against the surface of the salad for 30 seconds. If the tuna was packed in oil rather than water, drain and rinse it first โ oil-packed tuna releases more liquid when mixed.
- Parsley turns the mixture green after a few hours: This is oxidation, not spoilage. Stir it before serving and it wonโt affect the flavor. If appearance matters, hold the parsley and add it right before you eat.
Make-ahead notes
Store the finished salad in an airtight container in the refrigerator for up to two days. The yogurt base holds up better than mayo over time and wonโt break or weep much, but dress it at the table if youโre serving it on crackers โ a pre-dressed cracker goes limp fast. The diced tomato releases juice as it sits, so if youโre making this more than an hour ahead, keep the tomato separate and stir it in just before serving. Give the salad a quick stir before eating; any settled liquid on top can be stirred back in rather than drained off again.

Frequently asked questions
Can I use regular yogurt instead of Greek yogurt?
Regular yogurt is too thin and will make the salad watery. Greek yogurt is strained, which gives it the thick, creamy texture that actually binds the tuna. If Greek yogurt isnโt available, strain regular plain yogurt through a cheesecloth or coffee filter for 30 minutes before using.
What kind of canned tuna works best โ chunk light or albacore?
Either works, but chunk light tuna breaks into smaller flakes that mix more evenly with the other ingredients. Albacore is firmer and gives you bigger pieces, which some people prefer for texture. Both should be packed in water, not oil, for this recipe.
Can I make this without capers?
Yes, but youโll need to replace the briny, salty punch they provide. Finely chopped green olives or a few dashes of pickle relish are the closest substitutes. Without any replacement, the salad will taste noticeably flat.
How do I serve this โ what actually goes well with it?
Whole-wheat crackers or sliced crusty bread are the most practical options since the salad is thick enough to scoop. It also works well stuffed into half an avocado or spooned over a bed of arugula if you want to turn it into a more substantial plate.
Can I double the recipe for a group?
Yes, it scales up directly โ just use a larger bowl and a bigger colander for draining. The draining time stays the same at 2 to 3 minutes regardless of batch size.
Is dried oregano okay, or does it need to be fresh?
Dried oregano is what the recipe calls for and it works well here โ the other wet ingredients rehydrate it quickly. Fresh oregano has a sharper, more peppery bite; if you use it, cut the amount roughly in half since fresh herbs are more potent by volume.
