How to Make It
Heat oil in a large nonstick skillet over medium heat. Add onion and garlic, and sauté 5 minutes. Reduce heat to medium-low. Stir in salsa and tomato sauce; cook 20 minutes, stirring occasionally. Add corn, beans, olives, sour cream, and Creole seasoning; cook 4 minutes or until thoroughly heated. Keep warm.
Prepare grill or broiler. Place chicken on a grill rack or broiler pan coated with cooking spray; cook 5 minutes on each side or until done. Slice chicken lengthwise into 1/2-inch-wide strips.
Spoon the sauce over pasta. Top with grilled-chicken strips, and garnish with sliced pickled jalapeno peppers, if desired.
