In a skillet heat one tablespoon of olive oil and fry the onion, diced, chopped garlic and chilli, removing from it the seeds and finely chopped.

Mix in the tomato paste and fry a little.

Add the tomatoes with their juice and 150 ml of water. Tomatoes stretch. Let the sauce boil, cover and simmer for 10 minutes. Season to taste with salt, pepper and sugar.

Beans rinse to drain. Tuna to get out of the jar without the juice, mash. Add to the sauce with the beans and fish, and stir.

At the bottom of a rectangular baking dish evenly spread a thin layer a little sauce.

To lay sheets of lasagna, in turn, accurately sauce and sprinkling of cheese. 2 tablespoons of cheese and sauce to set aside for the top layer.

From top to grease the lasagna with the remaining sauce. Spread mozzarella torn with your hands, sprinkle with remaining cheese. Cover with a lid or foil and put bake in preheated oven at 175 degrees for 45 minutes. After 30 minutes, remove the cover (foil), to brown the cheese. I came up with 5 layers of dough, three of the sheet in each layer. Recipe source magazine "Just.Delicious" №6, 2010.
