Step 1: Brown the Ground Beef

Step 4: Layer the Ingredients in the Slow Cooker
Spray the inside of your slow cooker with non-stick cooking spray. Spread a thin layer of salsa on the bottom of the slow cooker. Place a layer of tortilla strips over the salsa. Spread half of the beef mixture over tortillas followed by half of black beans and corn. Add another layer of tortilla strips followed by remaining beef mixture, black beans, and corn. Top with remaining tortilla strips and pour remaining salsa over everything.
