I want to offer you a simple dish to prepare, which is very tasty both hot and cold.
Remove the onion, fry the pepper in the same oil.
Remove the pepper, fry the zucchini.
Mix sour cream with dry herbs, add garlic, allspice and salt.
In a frying pan without oil, put the fried vegetables, add sour cream, mix well.
Simmer on low heat under the lid for about 10 minutes (stir 2-3 times in the process), then make the fire to maximum, remove the lid and fry for 1-2 minutes, stirring.
