PEPPER STEAK WITH PORT, ZINFANDEL, AND MUSHROOM SAUCE

Steps:

• Melt 2 tablespoons butter in heavy large nonstick skillet over medium-high heat. Add shallots; sauté 2 minutes. Add mushrooms; cover and cook 5 minutes. Uncover and sauté until mushrooms are browned, about 10 minutes. Add flour and stir 1 minute. Add Zinfandel, Port, and broth. Boil until sauce thickens enough to coat spoon thinly, stirring occasionally, about 10 minutes. Season sauce to taste with salt and pepper. Set aside.
• Meanwhile, place steak between sheets of waxed paper. Using mallet or rolling pin, pound steak to 1/2-inch thickness. Coat both sides of steak with 3/4 teaspoon pepper and 1/2 teaspoon salt. Melt remaining 1 tablespoon butter in another heavy large skillet over medium-high heat. Add steak to skillet and cook to desired doneness, about 2 minutes per side for medium-rare. Transfer steak to work surface; do not clean skillet. Add mushrooom sauce to skillet; bring to simmer, scraping up any browned bits.
• Thinly slice steak; transfer to platter. Spoon mushroom sauce over and serve.
