Pulse untilwell-combined, about 10 times. Add cheese, pepper, butter and lemon juice and pulse until mixture forms a paste, about 20 times. Set aside. Beef Filets: Using a sharp paring knife, horizontally slit the side of each filet to create a pocket. Stuff each filet with an equal amount of pesto. Wrap one slice of bacon around each filet and secure with a toothpick. Rub olive oil over the filets just prior to cooking. Sprinkle with salt and pepper. Cook over medium-high heat on grill until meat reaches preferred doneness. Remove meat from grill and allow to rest 5 minutes. Variation: In a heavy skillet, pan-sear meat over medium-high heat for about 2 minutes per side, until browned. Finish cooking in a 350F pre-heated oven until meat reaches preferred doneness. Tip: Turkey bacon is a great, lower-fat alternative and still holds the filet together and keeps the pesto inside the filet while cooking.
