Dice and prepare all of the vegetables into small pieces.
In a large soup pot, heat the oil over high heat and add the onions, bell peppers and garlic. Cook, stirring often, for 2-3 minutes. Add the seasonings and stir to combine.
Add the ground beef and sausage to the pan and cook, breaking up the meat into small pieces, until the ground beef is cooked through, 5-6 minutes. Drain any excess grease.
Stir in the brown sugar, diced tomatoes, tomato sauce, and beans.
Cover and cook for 30-60 minutes on low heat, or until ready to serve.
Serve with toppings of your choice. Also great on yeast scones for navajo tacos.
