Ingredients You’ll Need
To make delicious Mediterranean Tuna Stuffed Peppers, you’ll need:
For the Peppers:
- 4 large bell peppers (red, yellow, or orange)
- Olive oil (for brushing)
- Salt and pepper
For the Filling:
- 2 cans of tuna in olive oil (drained)
- 1/2 cup cherry tomatoes, halved
- 1/4 cup finely chopped red onion
- 1/4 cup pitted Kalamata olives, sliced
- 1 tablespoon capers
- 1/4 cup chopped fresh parsley
- 1 garlic clove, minced
- 1 tablespoon lemon juice
- 2 tablespoons extra virgin olive oil
- Salt and pepper to taste
- Optional: 1/2 cup cooked quinoa or couscous
Step-by-Step Recipe
1. Prepare the Peppers
Start by washing your bell peppers. Cut them in half lengthwise and remove the seeds and membranes. Brush the insides lightly with olive oil and place them cut side up on a baking sheet. Roast in a preheated oven at 375°F (190°C) for about 15 minutes until they soften slightly.
2. Make the Tuna Filling
While the peppers are roasting, combine the tuna, cherry tomatoes, red onion, olives, capers, parsley, garlic, lemon juice, and olive oil in a large mixing bowl. If you’re using quinoa or couscous, stir it in now. Season with salt and pepper to taste.
3. Stuff the Peppers
Remove the roasted peppers from the oven and allow them to cool slightly. Spoon the tuna mixture into each pepper half, pressing down lightly to ensure they’re well filled.
4. Serve or Bake Again
You can serve Mediterranean Tuna Stuffed Peppers immediately if you prefer them at room temperature. For a warm, melty version, return them to the oven for another 10 minutes. Optional: sprinkle with feta cheese or a touch of shredded mozzarella before baking.

Storage and Meal Prep Tips
Mediterranean Tuna Stuffed Peppers hold up well in the refrigerator. Store leftovers in an airtight container for up to four days. To reheat, place in the microwave or warm in the oven at 300°F (150°C) for 10 minutes.
If you’re making them ahead, consider storing the tuna filling and roasted peppers separately and assembling just before eating to keep the texture fresh.
Frequently Asked Questions
Can I use fresh tuna instead of canned?

Yes! If you skip the quinoa or couscous, this dish is low in carbs and high in healthy fats and protein—perfect for keto or low-carb diets.
Can I freeze them?
It’s possible, but the texture of the peppers may change upon thawing. For best results, freeze the filling separately and use fresh peppers when ready to serve.
