Combine 1 teaspoon sage, 1/2 teaspoon salt, and 1/2 teaspoon pepper in a small bowl. Sprinkle both sides of pork with sage mixture.
Heat a large nonstick skillet over medium-high heat. Coat pan with cooking spray. Add pork; cook 3 minutes on each side or until browned. Remove from heat; set aside.
Add remaining 1 teaspoon of sage, white wine, and minced garlic to pan, scraping to loosen browned bits. Cook 1 1/2 minutes or until reduced to about 1/4 cup. Stir in seeded tomato and chicken broth, and cook 4 minutes or until slightly thick. Return pork and accumulated juices to pan. Cover and cook 1 minute or until heated. Sprinkle with 1/4 teaspoon kosher salt and 1/8 teaspoon black pepper.
