Cut onions, tomatoes, and peppers into halves or quarters. Peel the cloves of garlic. Form beef into two large patties. Season with salt, pepper, chili powder, and garlic powder.
Place seasoned vegetables and meat onto your preheated smoker and smoke at 200°F for about an hour.
Remove beef and veggies from smoker. Place beef into a heated dutch oven and cook until browned. Cut up veggies into a large dice reserving any juices that come from the veggies. Add the veggies, juice, and all remaining ingredients into the pot and simmer for 30 minutes, stirring occasionally.
Season to taste and serve. Top chili with shredded cheddar or sour cream.
Notes
*** To make chipotle puree simply blend a can of chipotles in adobo. You can freeze the remaining amount in an ice cube tray to use in other recipes.
