I took a saucepan, poured olive oil and added a piece of butter. Heat and melt the butter, put the garlic cloves crushed with the flat side of the knife. After a minute, I laid out the onion, browned it and added carrots. I didn't fry vegetables, didn't stew. 5 minutes after the carrots, lay out the eggplants. Simmer the vegetables until tender for 15 minutes. If you are going to cook caviar in a fast, then do not put butter, replace it with the one on which you will cook vegetables. With butter - such a festive option, and caviar turns out richer and, for me, so much tastier.
