Bring enough water to the boil in a saucepan for the gnocchi. Wash the vegetables, thinly slice the zucchini, dice the tomato and garlic. When the water boils, add salt, cook the gnocchi and zucchini for 2-3 minutes in the saucepan, then drain.
Meanwhile, sweat the garlic in olive oil, add the diced tomatoes and then the cream cheese and the liquid. Mix into a creamy sauce. Add the gnocchi and zucchini to the pan. Season to personal taste with salt, pepper and possibly fresh herbs (basil, parsley, etc.).
