Easy one for grilled catfish:

Rub the filets in olive oil and place in an aluminum foil pan. Make sure there is some extra oil to keep the filets from sticking. We then coat the filets with either Old Bay seasoning or a local product called Brother's Spicy rub. Grill for 15 to 20 minutes depending on thickness and type of grill. Don't even need to turn them. Very easy, but still healthy and good.
