Clean and pat dry 3 pieces of whole tilapia fish.
Put 7 green chilies, 6 garlic cloves, 1/2-inch ginger into a grinder, add little apple cider vinegar and salt. Grind it into a smooth paste.
Marinate the fish with the paste and keep it aside for 30 minutes.
Grease your grill tray with some extra virgin olive oil. Lay down fish pieces one by one.
Put inside the convection micro oven and grill for 4 minutes each side.
Once ready, garnish with some lime pieces and onion slices.
