Remove the head and intestines from the shrimp and rinse them under running water. Let them drain and in the meantime clean the mushrooms well from any soil. Cut them into wedges and set aside. In a pan add the oil, the garlic clove divided into 3 pieces and the parsley stalks. Fry and add the mushrooms. Cook over high heat for 7-8 minutes. Deglaze with the white wine. When the alcohol has evaporated, lower the heat and season with salt and pepper. Add the prawns and continue cooking for another 5 minutes. Stir occasionally. Serve with chopped parsley.
