Prepare the vegetables by chopping the bell peppers, celery, and onion, and dicing the jalapeno pepper.
Cook the bacon in a large cast iron skillet until lightly crisp, then remove and drain on a paper towel-lined plate.
Saute the vegetables in the bacon grease for about 5 minutes, until tender, then remove and drain as much bacon grease as possible.
Cook the ground beef in the same skillet with the bacon grease, breaking it into pieces about 1-2 inches. Cook one pound at a time so that the meat has enough room to brown and not steam.
Mix together the spice mixture ingredients in a small bowl.
In a slow cooker, mix the beef consomme or beef stock with the tomato paste. Add the Worcestershire sauce and spice mixture, and stir to blend. Taste the mixture and adjust spices as desired.
Add the cans of undrained tomatoes and beans, sauteed vegetables, and cooked ground beef to the slow cooker. Chop or cut the bacon into about ½ inch pieces and add to the chili mixture.
Cover and cook on low for about six hours.
Serve in a bowl with desired toppings.
