Cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente; drain and transfer to a large bowl.
In the meantime heat a large pan to medium-high. Add onion, garlic and zucchini and fry for a few minutes. Then canned tomatoes and cook for 3-4 minutes. Add cherry tomatoes, pepper, sugar, and 1 tsp. salt, stirring occasionally, until tomatoes burst and release their juices to form a sauce, 6–8 minutes.
Recipe Note
This recipe easily lends itself to using up any zucchini, mushrooms, tomatoes, or even a little wine :D
