Burgers: Surprise Burgers

Ingredients

• 
  1 pound lean ground beef


• 
  4 pineapple rings


• 
  1/2 cup ketchup


• 
  1/2 cup brown sugar


• 
  1 tablespoon prepared yellow mustard

Directions

1. 
   
   Preheat a grill for high heat.
   
   


2. 
   
   Divide the ground beef into four portions, and form patties around pineapple rings so that none of the pineapple is showing. In a small saucepan, mix together the ketchup, brown sugar, and mustard. Heat until sugar is dissolved. Set aside.

   Place burgers on the grill, and cook for about 5 minutes per side, or until well done. Spoon some of the brown sugar sauce over the burgers before serving.
