In a large heavy saucepan, heat the chicken broth, onion and re pepper flakes until the broth bubbles gently; cover and simmer for 3 minutes.
Add the spinach, cover and cook over moderate heat for 5 minutes or until the spinach has wilted. Sprinkle with the vinegar and toss.
Notes
Kale can be substituted for spinach but requires 10 minutes more cooking time.Want more delicious recipes for healthy living? Visit Ostego Nutrition today!
