Salad with Tuna, Corn & Olives
Open a can, drain it, pile everything into a bowl. That is genuinely the entire process for a lunch delivering 42 grams of protein and 559 calories with zero cooking.
Drained tuna sits on a bed of mixed greens with sweet corn, halved cherry tomatoes, sliced olives, and thin red onion rings. A generous pour of olive oil ties it together, and two slices of toasted whole wheat bread round it out into a full meal.
The tuna does double duty here. It delivers complete protein at a dose most people associate with a grilled chicken breast, plus the same omega-3 fatty acids found in fish oil capsules. Research suggests those capsules do nothing for muscle, but the protein packed alongside them in whole fish absolutely does.
Ingredients
- corn 2 ounces
- tuna, in water 5 ounces
- red onion 0.25
- olives 5
- cherry tomatoes 5
- mixed salad 1 handful
- olive oil 1.5 tablespoon
- bread, whole wheat 2 slices
Method
-
Rinse the corn in a colander under cold water. Let the tuna and corn drain in the colander.
-
Slice the red onion into thin rings, the olives into slices and halve the cherry tomatoes.
-
Put the mixed salad in a bowl and place the corn, tuna, red onion, olives and cherry tomatoes on top. Season with salt and pepper and drizzle the oil over the salad. Serve with the (toasted) bread.
Layer the ingredients in a sealable container for an easy grab-and-go lunch: greens on the bottom, tuna and corn in the middle, tomatoes and olives on top. Keep the olive oil in a small separate bottle and dress right before eating. Everything stays crisp for hours.
The omega-3 in your tuna is chemically identical to what's inside fish oil capsules. A meta-analysis tested whether that omega-3 helps build muscle across 15 different conditions, varying doses, durations, ages, and training levels. The result was the same every time: zero measurable effect on muscle protein synthesis. The protein alongside it in the fish is what does the work.
Fish Oil & Muscle - Meta-Analysis of 15 Testing ConditionsBehind this recipe
Do I still need fish oil supplements if I eat tuna regularly?
For muscle building, no. A meta-analysis found zero measurable effect of omega-3 fish oil on muscle protein synthesis across 15 testing conditions. The tuna in this salad already delivers the same EPA and DHA naturally, packaged with 42 grams of complete protein, which is the actual muscle-building nutrient. Fish oil may still have cardiovascular or anti-inflammatory value, but that is a separate conversation from muscle.
Read the full evidence reviewCan I use tuna in oil instead of water?
Absolutely. Just know the numbers change: oil-packed tuna adds roughly 8 to 12 extra grams of fat per can, pushing total calories past 630. For a cutting phase, water-packed keeps things leaner at the same protein dose. Outside a deficit, oil-packed adds richness and a few extra calories without any real downside.
Is 42 grams of protein too much for one meal?
No. The old claim that your body can only use 30 grams per meal has been thoroughly debunked. Research shows your body absorbs and uses well above 40 grams in a single sitting, the process just takes longer with larger doses. Forty-two grams is roughly half the daily protein target for someone losing fat at 80 kg, making this a solid anchor meal.
