In a large skillet, cook the beef and sausage over medium heat until no longer pink; drain. Add chili powder and cheese; cook and stir until cheese is melted. Spread a heaping tablespoonful onto each slice of bread. Place on a baking sheet.
Bake at 350° for 12-15 minutes or until edges of bread begin to crisp. Garnish with parsley. Serve warm. Yield: 2 dozen.
