In a heavy Dutch oven over medium-high heat, cook the bacon until the fat is completely rendered and the bacon is crisp, 4 to 6 minutes. Remove the bacon using a slotted spoon and set on the side. Add the cubed chuck, chili powder, cumin, and Southwest Essence to the hot rendered fat in the pan and cook, stirring occasionally, until the meat is well browned, 4 to 6 minutes. Add the onions, bell pepper, garlic and oregano and cook until soft, about 4 minutes. Add the tomatoes, broth, water and beans and bring to a boil. Reduce the heat to a simmer, partially cover the pot, and cook, stirring occasionally, until meat and beans are tender and sauce is thick and flavorful, about 1 1/2 to 2 hours. (Note: add more liquid if the sauce gets too thick before the beans are tender.) When the beans are tender and sauce is thickened, add the brown sugar, ketchup, and mustard and cook until thick and flavors have come together, about 20 to 30 minutes longer.
