Grilling is a great way to enjoy delicious, healthy, trout fillets. Simply place skinless, boneless trout fillets in your favorite citrus flavored marinade for about 10 minutes while your grill is heating up. Grill the fillets either on foil or in a fish pan (so they don’t fall through the grill rack) for about 5 minute per side or until cooked through and flake easily with a fork. You can brush more of the marinade on as you grill.
