Wash, peel and chop the vegetables and onions depending on the vegetables, drain the corn in a sieve.
Fry the onion small in a saucepan with a little oil until brown. Then put the remaining vegetables in the pot, put the lid on and let the vegetables cook a little in the steam.
When the vegetables have softened a little, add the tomatoes and tomato paste and season with salt, pepper, oregano or basil, depending on your taste. Let cook for another 5 - 10 minutes and you`re done.
Of course, other vegetables can also be used, which is why the recipe is also great for using leftovers.
