To prepare a broiled tilapia fish tacos with cilantro lime slaw recipe, you'll first need to prepare the fish. To do this, first you will want to preheat the broiler on medium-high heat. Then, place the thawed fish fillets in the pan and cook them for about 5 minutes on each side, or until they are just cooked through. Remove from the heat and set aside to rest for 10 to 15 minutes. Using tongs, carefully remove the skin from each fish and discard the bones. Cut each sliced fish into 12 inch (1.3 cm) thick slices. Place the slices on skewers and place them on the tortillas. Brush the tops of each tortilla with olive oil and season with salt and pepper to taste. Serve immediately.
