Preheat oven to 350 degrees F. Arrange half of the tortilla chips on an 11- or 12-inch ovenproof platter or pizza pan; set aside.
In a large skillet cook ground beef over medium heat until brown. Drain off fat.
Stir the black beans and the 1 cup salsa into the beef. Spoon half of the mixture over chips. Sprinkle with half the cheese. Bake in the preheated oven for 10 minutes or until cheese melts. Remove from oven. Top with remaining chips, beef mixture, and cheese. Bake for 10 minutes more or until cheese melts.
If desired, top with green onion, cilantro, jalapeno chile pepper, sour cream, and/or additional salsa.
