How to make
Boil the spaghetti. Drain and lightly mix them with a little olive oil to prevent sticking. Finely chop the onion, cut the carrots into thin slices, saute them in olive oil, add the pepper and garlic.
Once sauteed, add the tomatoes, mushrooms, finely chopped olives, bay leaf and oregano. Once the sauce thickens, remove it from the heat.
Serve the spaghetti topped with the sauce and sprinkled with grated cheese.
