A good food, it is tasty hot and cold - I learned to do it in Ukraine, when I went to my grandmother on vacation in the summer. You will definitely like it, is a bit like creamy roasted peppers.
Wash the zucchini, cut into medium-sized cubes.
If they are older, peel them and seeds, and then use what is left in the stew.
Put in a deep frying pan with a little oil, cook well over medium heat - until soft and browned.
Stir periodically.
Cut the onion into small pieces and cook with a little oil.
When the onion is lightly browned, add the diced tomatoes. Mix well and let the tomatoes soften well.
When the zucchini are ready, put the onion with the fried tomatoes on them and mix well.
Add sour cream, salt and mix again. Let it boil well for 5 minutes, then turn off the heat and let it cool a little.
As I said before, it is good and hot and cold, with a garnish of potatoes, rice, meat, etc.
Good appetite!
