Cut the onion into small cubes and fry, cut the meat into small strips or pieces. When the onions are golden brown, add the meat and continue to fry everything well, then add the rice and pour the broth on top. Either pour in the whole broth at once, or gradually fill up and let it boil until the rice is cooked through. Wash and cut the zucchini and cherry tomatoes and only add them at the end, otherwise it will be too mushy.
When the rice is done, add the beaker of sour cream and season with pepper. Salt is actually no longer needed because the broth is salty enough.
The great thing about this recipe is that all you have to do is get one pan dirty because everything is cooked there.
