Slice the red onion in half, then slice into thin strips. Dice the garlic cloves and ginger, then cut the chilis into small pieces. Over medium-high heat, add olive oil to a fry pan and cook the red onion, garlic, ginger and chilis until soft (5-10 minutes). Reduce heat slightly and add the tomato paste and can of tomatoes. Stir and add the ouzo, oregano, and lemon juice. Let cook for 1 5 minutes until the flavors infuse. If the sauce becomes dry, add some chicken stock or water to re-hydrate as needed.

Add the raw prawns, cover the pan with a lid and let cook until the prawns turn pink (do not overcook). While the prawns are cooking, pre-heat the oven broiler to 500 F. Sprinkle some crumbled pieces of feta cheese on top and place the pan on the top shelf of the oven. Broil for 3-6 minutes until the feta cheese melts. Serve with chopped parsley on top and several lemon slices.
