Drizzle some olive oil over the filets. Season with salt and pepper then the cayenne pepper and garlic powder. Marinate for at least 15 minutes before grilling.
Grill filets on high heat for 1 minutes per side to sear. Reduce heat to medium and continue grilling about 3 minutes per side. Serve with you favorite side dish. Enjoy!
