Prepare rice according to package directions, omitting salt and fat.
While rice cooks, heat oil in a large nonstick skillet coated with cooking spray over medium-high heat.
Combine broth and next 6 ingredients (broth through pepper). Add onion to pan; sauté 2 minutes. Add steak; sauté 5 minutes or until desired degree of doneness. Stir in broth mixture; cook 10 seconds until slightly thick, stirring constantly. Serve over rice with lime slices.
