  1. Place cubed meat in the bottom of your slow cooker.
  2. Place peppers, onion, mushrooms and minced garlic over meat.
  3. In a small dish combine all spices with a spoon. Sprinkle spice mixture over meat and veggies.
  4. Add water and cook on LOW for 7-8 hours until meat is cooked through and tender.
