A very simple, healthy and tasty recipe for cooking fish. Fish is good both as a hot food and as an appetizer.
Wash the fish fillet, remove the skin, cut into medium pieces and arrange in an oven tray.
Salt and pepper to taste.
Grease the fish pieces with mayonnaise.
Cut the onion into small pieces and place over the mayonnaise.
Grate the cheese over the onion and put the tray in the oven for 30-40 minutes.
When browned, remove the fish from the oven.
Serve sprinkled with lemon juice.
Good appetite!
