In a 4-6 quart slow cooker combine the stew meat, beans, tomatoes, corn, pepper, beef broth, and bouillon cube. The liquid should come up to the top, so if you use a larger slow cooker, add more water or broth if needed to fully cover the ingredients.
Cook on low for 7-8 hours.
In the final 30 minutes of cooking time, add in the cumin and flour and mix this together, then let cook an additional 30 minutes. This will allow the stew to thicken a bit.
Serve.
Notes
This is wonderful served with tortilla chips and cheese.
