Preheat your grill or stovetop grill pan to medium-high heat.
Season the Desert Harvest Catfish fillets with salt and pepper on both sides.
Place the fillets on the grill and cook for 3-4 minutes per side or until the fish is opaque and flakes easily with a fork. Cooking time may vary depending on the thickness of the fillets.
Remove the cooked fish from the grill and let it rest for a few minutes. Then, flake the fish into smaller pieces using a fork.
Take a large romaine lettuce leaf and spoon some flaked catfish onto it. Add desired toppings such as sliced avocado, sliced radishes, sliced red onion, and a squeeze of lime juice.
Drizzle the cilantro cream over the fish and toppings.
Repeat the process with the remaining lettuce leaves and ingredients.
Serve the low-carb fish tacos immediately, and enjoy!
Note: Feel free to customize the toppings and add any additional low-carb ingredients that you prefer, such as diced tomatoes, shredded cabbage, or hot sauce.
