At home, combine onion and garlic in a heavy-duty zip-top plastic bag; seal. Combine potato, carrot, bell pepper, and soup mix in a heavy-duty zip-top plastic bag; seal. Place bags in cooler.
Cook the beef, onion, and garlic in a large Dutch oven over hot coals (or in a Dutch oven over medium-high heat if at home) for 10 minutes or until browned; stir to crumble. Add potato mixture and broth; cook 15 minutes or until vegetables are tender. Add beans, corn, salt and black pepper; simmer 10 minutes.
