Place bacon in a Dutch oven and cook over medium-high heat, turning occasionally, until evenly browned and slightly crisp, about 10 minutes. Drain bacon pieces on paper towels. Drain off all but 2 tablespoons bacon grease from pot.

Melt butter in the pot with the remaining bacon grease over medium heat. Add onion, red bell pepper, and jalapeno. Sautee until just softened, 5 or 6 minutes. Add minced garlic and saute for 1 minute. Whisk in flour and stir until completely incorporated, about 2 minutes.

Season with salt, pepper, cumin, chili powder, and cayenne pepper. Gradually whisk in Swanson® Unsalted Chicken Broth, stirring to prevent flour from clumping. Bring to a boil over medium-high heat. Add potatoes and green chilies; reduce heat to medium-low. Simmer until vegetables begin to soften, about 12 minutes

Stir in frozen corn and chopped chicken. Add 1/2 cup of cooked bacon pieces. Add half and half; stir. Reduce heat to low; simmer very slowly until chicken and corn are heated through, 8 to 10 minutes. Remove pot from heat. Stir in 1 cup grated Cheddar cheese until cheese melts.

Pour soup into bowls and garnish with reserved bacon, grated Cheddar cheese, cilantro, and green onions.
