Why this meal fits low carb
Tuna salad stuffed into mini pepper halves is a complete no-cook lunch format: the tuna supplies the main protein, mayonnaise binds the filling, and celery, onion, and peppers provide contrast without bread. Using the peppers as cups also makes the two-serving batch easy to divide. The listed estimate assumes plain tuna and mayonnaise without sweet relish or a sweetened dressing.
Swaps
Canned salmon or cooked shredded chicken can replace tuna, but their texture may require a little more or less mayonnaise. Cucumber boats or celery sticks can replace the mini peppers. Skip sweet relish unless you have checked and included its label values; chopped dill pickle gives a similar tang with more predictable portioning.
Meal prep
Mix the tuna filling and refrigerate it in a covered container for up to two days. Wash, halve, and dry the peppers separately. Stuff them shortly before serving so they remain crisp and the filling does not become watery. For transport, pack the filling and pepper halves in separate compartments and assemble at lunch.
Choose and prep the ingredients
Drain the tuna thoroughly so the filling stays in the pepper cups. Tuna packed in water or oil both work, but the final texture will differ; oil-packed tuna may need slightly less mayonnaise. Choose firm mini peppers without wrinkled skin, and halve them lengthwise to make stable cups. Mince the onion finely so no bite overwhelms the filling, then add lemon gradually because brands of mayonnaise vary in acidity.
Serve it well
Spoon equal amounts of filling into all eight pepper halves, then divide four halves per serving. If the peppers tip, trim only a very thin strip from the rounded side without cutting through the cup. Serve cold, or let the tuna mixture sit out just long enough to lose its refrigerator chill before filling the peppers.
Ingredients
- 2 cans tuna in water, drained
- 3 tbsp mayonnaise
- 1 celery stalk, diced
- 2 tbsp red onion, minced
- 4 mini bell peppers, halved
- Salt, pepper, and lemon juice
Instructions

Tips
Swap peppers for cucumber boats for even fewer carbs.
