1. Start the recipe by preparing the marinade for the beef. To do this, peel and crush the garlic clove. Blend the sun-dried tomatoes with the garlic clove and two tablespoons of oil.
2. Using a food brush, brush the beef fillets with the marinade and refrigerate for at least 1 hour, adding the thyme.
3. Sear the beef fillets for 1 to 2 minutes on each side in hot cooking fat.
4. Arrange the plates nicely and serve the meat with some sun-dried tomatoes.
