Wayne's Sweet and Spicy Beef Chili

Heat oil in a large skillet over medium heat. Add onions and saute until translucent, 6 to 9 minutes. Add bell peppers. Saute until soft, stirring occasionally, 6 to 9 minutes. Stir in serrano peppers and hot chili seasoning; continue mixing for another 3 to 6 minutes. Transfer onions and peppers to a large pot.

Heat the same skillet over medium-high heat. Cook and stir ground beef in the hot skillet until browned and crumbly, 6 to 9 minutes. Transfer to the large pot.

Pour kidney beans, Northern beans, tomato puree, and diced tomatoes into the pot. Add ketchup in order to achieve desired consistency. Stir in habanero pepper and sugar. Simmer chili over medium heat, stirring occasionally, about 36 minutes. Top with Mexican cheese blend.
