Saute ground meat over medium heat until no longer pink. Sprinkle on garlic powder, cayenne and Taco seasoning mix. Stir well. Add drained black beans. Mix thoroughly; remove from heat. When meat mixture has cooled to room temperature, stir in cheese and onions. TO MAKE WON TON: Place a teaspoon of the mixture onto the middle of each won ton wrapper. Wet the edges of the wrapper with water, fold the wrappers over to form triangles, and seal the edges, pinching them together. Moisten bottom side of LEFT corner and upper side of RIGHT corner. Fold left corner up toward you, and fold right corner over left; seal together. Fry several won tons at a time in hot oil (375 degrees F) until golden brown. Drain well on paper towels. Serve with fresh Mexican salsa or guacamole. Makes approximately 100 won tons.
