Grilled Fish Fillet in Spicy Sauce Recipe

: Place the garlic, shallots, lemon grass, turmeric, galangal powder, chilies, salt and pepper in a food processor and process until a paste is formed, adding the oil to help the grinding. Cut the fish into large bite-sized pieces. Place the fish in a bowl with the spice paste, toss well, cover and refrigerate for 15 minutes. Place the fish on a foil-lined grill tray and cook under a hot grill for 3 to 4 minutes, turning the pieces over so the fish browns on all sides. Arrange the fish on a serving place and sprinkle over the nuoc cham sauce. Serve immediately with rice.
