Cook first 3 ingredients in a large nonstick skillet, stirring until beef crumbles and is no longer pink. Drain and return beef mixture to skillet. Add 1/4 cup water and taco seasoning.
Simmer 3 to 4 minutes or until liquid evaporates. Remove from heat, and stir in cheese.
Spoon 1 level tablespoon of mixture onto center of each won ton wrapper.
Moisten won ton wrapper edges with water. Bring corners together, pressing to seal.
Pour oil to a depth of 2 inches into a Dutch oven; heat to 365°. Fry filled won tons, in batches, 2 minutes on each side or until golden. Drain on wire racks over paper towels.
