Heat the oil in the pan and then add the onion and red pepper. Sprinkle on some salt and pepper and let them cook for 5 minutes, stirring frequently. Add the garlic cloves and let them cook for 1 minute, until fragrant.
Add the ground beef and stir with a wooden spoon, breaking the meat into chunks. Brown the ground beef thoroughly. Add the beans and the rest of the ingredients.
Lower heat to 250ºF and continue cooking with the lid on the electric skillet for 10 minutes.
If you feel it is too thick, you can pour the reserved liquid from the beans into the chili, until desired consistency. If needed, season again with salt and pepper, to taste.
