Follow these easy steps to create your Slow Cooker 4-Ingredient Slumgullion:

1. Brown the Meat: In a skillet over medium heat, brown the ground beef (or turkey) until fully cooked. Drain any excess fat.
2. Combine Ingredients: In the slow cooker, combine the browned meat, diced tomatoes with green chilies, kidney beans, and uncooked macaroni pasta.
3. Mix Well: Stir the mixture until all ingredients are well combined.
4. Add Liquid: If the mixture seems too thick, you can add a bit of water or broth to reach your desired consistency.
5. Set the Slow Cooker: Cover the slow cooker and set it to cook on low for 6 to 8 hours or on high for 3 to 4 hours.
6. Stir Occasionally: If possible, stir the mixture occasionally to ensure even cooking.
7. Check for Doneness: About 30 minutes before serving, check the pasta for doneness. It should be tender but still hold its shape.
8. Serve: Once everything is cooked through and the flavors have melded, it’s ready to serve!
