  • 1 lb ground beef See Recipe Notes
  • 2 cups chopped onion, bell pepper, celery blend See Recipe Notes
  • 1 16 oz jar of salsa
  • 1 15 oz can of black beans, drained and rinsed
  • 1 14.75 oz can of southwest or fiesta corn, drained
  • 2 10 oz cans of red enchilada sauce
  • 2 tbsp butter
  • 2 tbsp chili powder
  • 1 tsp cumin
  • 1 tsp minced garlic
  • 1 tsp onion powder
  • 1 tsp oregano
  • 1/2 tsp cumin seed
  • 1/2 tsp black pepper
  • 1 cup long grain white rice See Recipe Notes
  • 2 cups water
  • 1 lime
  • Your favorite toppings of choice: a few drops of fresh lime juice, shredded cheese, avocado, sour cream, greek yogurt, guacamole, lettuce, tomato, etc.


  • Brown the ground beef and drain. Add to slow cooker.
  • Add remaining ingredients to the slow cooker. Mix well. Cook on high for 3 hours or low for 4-5 hours or until rice is cooked.
  • Top with your favorite items such as a squeeze of fresh lime, chopped cilantro, avocado, shredded cheese, green onions, sour cream, lettuce, tomato, etc.  Eat with tortilla chips or corn chips.


NOTES: (1)  You can use cooked ground turkey, cooked ground chicken, or cooked chopped or shredded chicken instead of the cooked ground beef.
(2)  I like to use the frozen seasoning blend to save myself some chopping time.  However, you can use fresh bell pepper, onion, and celery if you desire.  I would use 1 cup chopped fresh onion, 1 cup chopped fresh bell pepper, and 1/2 cup chopped fresh celery.
(3)  If you plan to use brown rice instead of white rice, you'll probably need to cook it longer.  Perhaps as much as one hour longer using brown rice.
