This was our dinner last night. First time I made it so I was a bit worried but it tasted good so I'll be doing it again! And... it's pretty easy!
Just put olive oil, onions and garlic in a pan, let it fry for a bit. Add the fish and let it cook slowly. Once it's done remove the fish and add a sauce of 1 egg and lemon juice previously stirred. Add the fish again, salt and pepper and you're done! Serve with rice or vegetables or both!
