Combine flour and salt in a heavy-duty, zip-top plastic bag. Add pork; seal bag, and shake until pork is coated.
Melt butter in a large nonstick skillet coated with cooking spray over medium heat. Add pork; cook until browned, turning once. Remove from pan. Add wine, garlic, bouillon granules, and pepper to pan; bring to a boil. Reduce heat, and simmer, uncovered, 2 minutes. Return pork to pan; cover and simmer 2 minutes or until sauce thickens. Serve over pasta, if desired.
