In a large skillet over medium-high heat, cook the ground beef and onion until the beef is browned and the onion is translucent. Drain excess grease.
Add the minced garlic and taco seasoning to the skillet. Cook for 1 minute while stirring.
Pour in the enchilada sauce, beef broth, black beans, and corn. Stir to combine and bring to a light simmer.
Gently fold in the corn tortilla strips until they are evenly distributed and coated in sauce.
Reduce heat to low and simmer uncovered for 5 to 8 minutes, or until the sauce has thickened and the tortillas have softened.
Sprinkle the shredded cheese over the top of the mixture. Cover the skillet with a lid for 2 minutes until the cheese is fully melted.
Remove from heat and garnish with fresh cilantro before serving.
