Tuna, Egg, and Cheese Casserole

Drain the tuna and remove all the oil.

In a skillet, heat a little olive oil and sauté the diced onion and red bell pepper until tender.

Add the tuna to the onion and pepper mixture, cook for one more minute, and then remove from heat.

Transfer the mixture to a bowl and add the eggs, which should be beaten beforehand, along with three tablespoons of grated Parmesan cheese. Season with salt and sweet paprika, and process everything until it forms a paste.

In a baking dish previously brushed with oil, pour the tuna mixture and sprinkle the remaining grated cheese on top. Bake in a preheated oven at 180°C (350°F) for 20 minutes.
