Pour olive oil into the pan. Steam the onions in it until translucent. Cut the ravioli into finger-thick strips and add. Then add the garlic, zucchini, paprika and tomatoes and simmer, putting the lid on. After about 5 minutes add the tomato puree, salt, pepper and sugar. If you like, you can now add the chopped herbs. Stir and simmer again with the lid closed.
