4 servings (serving size: 1 pork chop and 1/2 cup sauce)
Heat a large nonstick skillet over medium-high heat. Place 1/4 cup flour in a shallow dish. Dredge pork in flour. Coat pan with cooking spray. Add pork to pan; cook 4 minutes on each side or until browned. Remove pork from pan.
Add shallots, garlic, and mushrooms to pan; sauté 3 minutes or until moisture evaporates. Add remaining 2 tablespoons flour and thyme to pan, and cook for 1 minute, stirring well. Combine chicken broth and Marsala, stirring until smooth. Gradually add broth mixture to pan, stirring constantly with a whisk; bring to a boil. Reduce heat and simmer 2 minutes or until sauce thickens.
Return pork to pan; cook 2 minutes or until desired degree of doneness, turning to coat. Sprinkle with salt and pepper.
