Cut prepared Cornish hen into 4 parts, cut the tendons in joints of legs and wings, and slightly point the meat. Season hen with salt and pepper, put skin side down into oil in a preheated skillet and fry until browned. Turn pieces over and fry on the other side, then add 2 tbsp of sour cream and continue braising on low heat 10-15 minutes. Separately fry tomatoes cut in half, and peeled and sliced into circles zucchini. To serve transfer hen to a heated serving plate and garnish with slices of fried zucchini and tomatoes, pour strained juices on top and sprinkle with finely chopped dill or parsley leaves.
