FAQ
Can I use canned tuna?
Yes, drained canned tuna works. For more flavor, use tuna packed in oil; for fewer calories, choose water-packed.
Is baking required?
Baking helps soften the tomatoes and meld flavors. You can serve them warm or at room temperature after baking; or, if you prefer, assemble and serve without baking, but the texture will be firmer.
How should I store leftovers?
Cool and refrigerate in an airtight container for up to 2 days; reheat gently or eat cold.
Can I make this vegetarian or vegan?
Yes. Replace tuna with chickpeas or white beans; note the protein amount will be different.
Are these gluten-free?
Yes, naturally gluten-free; check for cross-contamination if using other ingredients.
What size tomatoes should I use?
Medium to large ripe tomatoes work best; four medium tomatoes yield about two servings; adjust for size. Hollow out the pulp before stuffing.
Can I freeze stuffed tomatoes?
Not recommended; freezing can affect texture; best enjoyed fresh or refrigerated.
Can I customize the flavors?
Yes—try other herbs like basil or cilantro, or add capers or paprika; salt to taste.
What should I serve it with?
Pair with a green salad, whole grains, or crusty bread for a balanced meal.
What allergens are in this dish?
Contains tuna (fish) and onion; if you have allergies, omit or substitute, and check lemon juice ingredients if needed.
