In a large mixing bowl, combine flour and 1/2 teaspoon each of: cumin, garlic powder, onion powder, and Mexican oregano.
Dredge sirloin cubes in spice mixture until well coated.
Add diced onion to large sauté pan over medium heat with a Tablespoon of your choice cooking oil.
Once onion begins to caramelize, add meat and diced peppers. Stir occasionally until meat starts to brown on the outside (about 2-4 minutes).
Once meat is just browned on the outside, add 4 cups beef stock to pan, along with 1/2 teaspoon each of: cayenne pepper, cumin, garlic powder, onion powder, Mexican oregano, and salt. Add 1/4 teaspoon black pepper, 1 tablespoon tomato paste, 3 pressed garlic cloves, 2 bay leaves, and 1 can of stewed tomatoes.
Stir well then add cubed potatoes, sliced carrots, and 1 quartered onion. Reduce heat to low and allow to cook for 1 1/2 to 2 hours. (2 hours is more than sufficient, but the longer it stews, the more tender the meat will be).
