Green Chilie Burrito Meat

I love love love authentic mexican food, and where I live (Minnesota), it's unheard of!  So, I came up with this recipe to satisfy my craving!  :)

Here's what you need:

1 3-lb beef roast
1 small/medium can (diced) green chilies (do not drain)
1 Tbsp minced garlic
1 to 1 1/2 tsp ground cumin (depends on how much you personally like the flavor of cumin)
1/4 tsp or less ground black pepper
1 carton of beef or veggie broth (I did not have any broth, so I used 3 cups of water, and two beef boullion cubes broken up)
6-8 baby red potatoes peeled/diced into small pieces (optional)

Place all ingredients except potatoes into a crockpot.  Cook on low for 6-8 hours.  When you have about 3 hours of the cook time remaining, put your potatoes into the pot. 

*If you have any leftover meat, use it the next night for tacos!
