Press pepper into both sides of steaks. Coat a large nonstick skillet with cooking spray, and place over medium-high heat until hot. Add steaks; cook 2 minutes on each side or until browned. Reduce heat to medium-low; cook 4 minutes on each side or until desired degree of doneness. Remove steaks from skillet; set aside and keep warm.
Add broth and brandy to skillet; bring to a boil, scraping skillet to loosen browned bits. Reduce heat and simmer, uncovered, 2 minutes or until mixture is reduced to 1/2 cup. Remove from heat, and stir in sour cream and salt with a whisk. Spoon 3 tbsp sauce over each steak.
