Mango Burgers with Avocado Cream

Wipe grill with a vegetable oil and heat to medium. In a small mixing bowl, combine avocado and cream cheese. Stir until well blended, add lime juice and salt, then stir until blended. Cover surface with plastic wrap and chill until needed. In a large mixing bowl, combine all burger ingredients and blend well. Shape into 6 large round patties. Grill burgers over medium heat 10 to 15 minutes or until meat is no longer pink, turning once. When burgers are almost done, place buns flat side down on grill to toast until golden brown. Remove buns from grill; spread avocado cream on flat sides of buns. Place bun bottoms on 6 plates. Add mango slices, burgers, and bun tops; close sandwiches and serve.
