California Walnut Pesto

1. Combine basil, walnuts, olive oil and garlic in food processor. Pulse until well-combined, about 10 times.
2. Add cheese, pepper, butter and lemon juice and pulse until mixture forms a paste, about 20 times. Set aside.

Beef Filets

1. Using a sharp paring knife, horizontally slit the side of each filet to create a pocket.
2. Stuff each filet with an equal amount of pesto. Wrap one slice of bacon around each filet and secure with a toothpick.
3. Rub olive oil over the filets just prior to cooking. Sprinkle with salt and pepper.
4. Cook over medium-high heat on grill until meat reaches preferred doneness. Remove meat from grill and allow to rest 5 minutes.

Variation

1. In a heavy skillet, pan-sear meat over medium-high heat for about 2 minutes per side, until browned.
2. Finish cooking in a 180°C / 350°F pre-heated oven until meat reaches preferred doneness.
