Preparation

Season the filets with salt and pepper. Tie a slice of bacon and a rosemary sprig around each steak with kitchen string.

Heat butter and oil over medium-high heat in a heavy skillet or sauté pan until it shimmers. Add steaks and brown well, approximately 2-3 minutes per side (or to your desired doneness), adjusting heat as necessary to prevent fat from smoking.

In the meantime, heat Portobello Mushroom Sauce according to package instructions. Transfer filets to plates, top with sauce and serve immediately.
