Stir in the taco seasoning mix and cook for 1 minute. Then add the diced tomatoes with green chilies (including juice) and stir to combine. Remove from heat.

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 the tortillas. Add half of the black beans and half of the corn. Repeat layering with another layer of tortilla strips followed by remaining beef mixture, black beans, corn, and top it off with remaining tortilla strips and salsa.
