Easy, sweet roasted bell peppers filled with a Mediterranean tuna salad and topped with cheese.

Watch the Video:
These tuna stuffed peppers could not be easier, plus you’ll have dinner on the table in just thirty minutes. The bell peppers are roasted in the oven until soft and sweet. The flavorful tuna salad is the same one I eat on crackers and bread, but it’s perfect for stuffing these smoky peppers. I like using red peppers because they get nice and sweet, but any color pepper will be good. If you can find tuna packed in oil, it’s so much more flavorful. However, if you only have tuna packed in water, drain the tuna and add a bit more olive oil when making the tuna salad. It makes the best quick and delicious weeknight meal.

Serving
If you’re watching your carbs, this is it. I’m not, but I would eat this often if I were. Cooking the pepper just until tender helps them to keep their shape and works best for stuffing. The slightly charred, sweet roasted pepper goes so well with all the flavors of the tuna salad, and when you get a bite with a caper, it’s a beautiful surprise. These stuffed peppers are so filling you won’t need anything else, and your family is going to love them. Kali Orexi!
