Brown and crumble the ground beef along with the diced onion in a large skillet over medium-high heat. Once the beef is no longer pink, drain any fat and return the skillet to the stove top.
Add in the seasonings (chili powder, garlic salt, cumin and oregano) and stir until fragrant, about 30 seconds. Pour in the enchilada sauce, salsa and black beans and bring the mixture to a simmer.
Stir in the chopped corn tortillas, allowing them to soak up some of the enchilada sauce. Once heated through, top with the shredded cheese. Cover the skillet with a lid and allow the cheese to melt. Top with your favorite taco toppings and enjoy!
