Directions:

Heat 1 tablespoon oil in large nonstick skillet over medium heat and cook chicken, turning once, 8 minutes or until thoroughly cooked. Remove chicken and set aside.

Heat remaining 1 tablespoon oil in same skillet and cook onion over medium heat, stirring occasionally, 5 minutes or until tender.

Add Sauce and spinach. Cook, stirring frequently, 2 minutes or until sauce is hot and spinach has wilted. Return chicken to skillet; heat through.

Tip:
Also delicious with shrimp instead of chicken. Decrease cooking time to 3 minutes or until shrimp turn pink.
