Here is a receipt I have used twice already and every time it just gets better. In fact, it was the first 'dish' I made using my crockpot!

Easy Slow Cooker Carne Guisada - "Carne guisada is a hearty Mexican-style beef stew. It is excellent with tortillas or cornbread, and is also great as a burrito filling."

3 pounds chuck roast, cut into 1 1/2-inch cubes (I used 2 lbs as 3 lbs is way too much for 2 people. I also tailored the rest of the recipe and I have marked where...)
3 medium potatoes, unpeeled and diced (I used 2)
1 medium onion, chopped
2 red bell peppers, cut into strips (I used one)
3 cloves garlic, crushed
1/4 cup all-purpose flour
1/4 cup chili powder (instead, I added fresh jalapenos)
1 teaspoon cumin (a little less, not to much)
1 teaspoon salt (actually, I only added in a dash of salt)
3 cups beef broth (I used 2 cups)

Combine beef, potatoes, onion, peppers, and garlic in a large bowl. In a small bowl, mix together the flour, chili powder, cumin, and salt. Toss the beef mixture with the flour mixture until evenly coated. Place the mixture into a slow cooker, and pour in enough beef broth to barely cover the meat. If you don't have quite enough, you can fill the rest of the way with water. Now becareful - the meat can float in the liquid, so make sure you pat the meat down after adding the 2 cups of broth to ensure that there is enough liquid. As I have learned, a little liquid goes a long way!

Cook on Low until the beef is tender, 6 to 8 hours.

I served this with sweet corn bread and sour cream. YUMMY!
