Fire up your grill to about 200F (or set it on the low heat smoke setting) and add soaked wood chips to create smoke.
Spray the filets with a little olive oil and then rub on the seasonings, making sure the top and bottom are covered. Also, spray the filets one final time before adding to the grill.
Place the filets on a soaked wooden plank OR a cast iron grill and then add them to the smoker/grill. Smoke on low heat for about 2 hours.
Garnish and enjoy!
