Creating your very own Slow Cooker Cowboy Casserole is easy with these simple steps:

1. Brown the Meat: In a skillet over medium heat, brown the ground beef. Drain off any excess fat.
2. Combine Ingredients: In the slow cooker, combine the brown beef, black beans, pinto beans, corn, diced tomatoes, chili powder, cumin, garlic powder, onion powder, salt, and pepper. Stir well to mix everything together.
3. Cook: Cover the slow cooker and set it to low for 6-8 hours or high for 3-4 hours.
4. Add Cheese: About 30 minutes before serving, sprinkle the shredded cheese on top and cover again to let it melt.
5. Serve Chips (Optional): If desired, crush tortilla chips just before serving and sprinkle them on top of the casserole for added crunch.
6. Garnish: Finish by garnishing with fresh cilantro if you like.

These steps will guide you to create a flavorful and comforting cowboy casserole with ease!
