Make the chili: In a large skillet, cook ground beef, stirring occasionally until lightly browned, about 5 minutes. Once meat is browned, remove grease and set beef aside. In same skillet, combine vegetables, bacon, beef base, chili seasoning, worcestershire, and oil. Cook for 15 minutes, or until vegetables have softened. Add ground beef back to skillet. Slowly stir flour into mixture and continue to cook for 20 minutes.
To assemble: Cut open single-serving Fritos bags and ladle in a scoop of chili. Top with grated cheese, diced onions, and pickled jalapeños.
