Cook the bacon in a large stockpot over medium heat until it begins to crisp. Spoon off the bacon fat, except for a thin coating. Add the peppers and onion to the bacon and continue cooking, stirring frequently, until the vegetables are tender.
Add the sweet potatoes, chicken broth, and chipotles and simmer, covered, 15 minutes or until the potatoes are tender. Stir in the corn, milk, and salt; heat through. Serve with quesadillas and garnish with cilantro.
Monterey Jack Quesadillas:
Heat tortillas in a preheated 350 degree F oven until warm. Top each with some shredded Monterey Jack and a few cilantro leaves. Top each with another tortilla. Heat until cheese is melted.
