Brown ground beef in a large Dutch oven over medium-high heat, stirring constantly, 8 to 10 minutes or until meat crumbles and is no longer pink; drain. Return to Dutch oven.

Stir pinto beans, next 8 ingredients, and 2 cups water into beef; bring to a boil. Reduce heat to medium-low. Simmer, stirring occasionally, 30 minutes. Serve with desired toppings.

The Quesadilla: Sprinkle shredded pepper Jack cheese on 6 (6-inch) fajita-size flour tortillas. Fold tortillas in half, press gently to seal, and spread butter on each. Cook quesadillas in a hot skillet 2 to 3 minutes on each side until browned. Cut into wedges.
