Saute the onion and garlic in a little oil, stir in the tomato paste and paprika powder and fold in the tuna.
Add the zucchini pieces and the tomatoes and mix everything well. Add the salt, pepper and the pasta seasoning and the parsley and grated cheese and mix well with the pasta.
Sprinkle the tuna and vegetable pasta with Parmesan cheese.
