Allow to rest for 10 minutes or until the chilies are soft and everything is lightly cool.

Step 5

Add tomatoes, onion, and chilies to a blender with cumin and garlic.

Step 6

Heat oil on a cooking pan over medium heat. Add meat and cook stirring constantly until browned on all sides.

Step 9

Pour over the sauce, mix, then add 2 cups of water (or beef stock). Bring to a boil.
