This is the pasta I (or most Italians) do on a regular basis when we don't have any special idea on what to cook, hehe. This is the way I do it. This time I however cooked it au gratin at the end with readily grated regular cheese and parmesan on top. Yum!
270 g penne (I prefer my penne rigate and integrali)
2 cloves garlic
1 big onion
70 g tomato sauce
2 tablespoons white vinegar or apple vinegar
a tiny pinch of dried peperoncino
basil (fresh or dry)
Cook the pasta in salted water. Grind the garlic and chop the onion quite fine. Peel the tomatoes and remove their insides. Cut the tomatoes into sticks. Fry the garlic and onion on a pan with olive oil, and when they have gained a little bit of colour, add the tomatoes. Add salt and pepper plus a tiny bit of peperoncino. Pour in the 2 tablespoons of vinegar. Cook on heavy heat for some 2-3 minutes and then lower the heat by half. Add the tomato sauce and cook for 6-8 minutes still. At the end add the basil.
Mix the pasta and the sauce together and pour it on an oven baking plate. Add some regular cheese and parmesan on top.
Bake in the oven set to the gratin function for 10 minutes.
