Marinate the chicken in the soy sauce and lemon juice for 30 minutes.
Warm up the olive oil. Simmer the onions, garlic and lemon peel, add the rice, stir-fry until the rice is translucent. Add the thyme leaves, deglaze with the prosecco and a little bouillon. Let the rice cook for about 20 minutes and keep adding a little bouillon while stirring until the rice is cooked through. In the meantime, brown the chicken well under 2 servings and keep warm. When the rice is done, stir in the creme fraiche, add the chicken and stir in, season with salt and pepper. Sprinkle with a little parmesan if you like. Serve immediately.
