Yield: 18 muffins
Preheat oven to 350 F
Spray muffin pans with nonstick cooking spray or line with paper baking cups (2 1/2- inch; 18 count).
Place one piece of broccoli in each cup.
In a large bowl add muffin mix, onion, cheese, eggs and melted butter and stir just until combined. Fill greased muffin cups (or paper baking cups) three-fourths full covering the broccoli.
Bake for 20 to 25 minutes or until a toothpick comes out clean. Cool for 5 minutes before removing from pans.
