Step 1

Heat oil in a large cast-iron skillet over medium-high. Add chicken, and cook, stirring occasionally, until seared on all sides, about 3 minutes. Add bell peppers, onion, chili powder, cumin, salt, paprika, and garlic powder; cook, stirring often, until peppers are slightly softened, about 4 minutes.

Step 2

Stir in pasta and water (some of the pasta will not be submerged in water). Bring to a boil over medium-high. Cook, stirring occasionally, until pasta is al dente and cooking water is thickened, 12 to 14 minutes.

Step 3

While pasta cooks, preheat oven to broil, with oven rack about 6 inches from heat.

Step 4

Remove pasta from heat. Stir in cilantro, cream cheese, and 1 cup of the pepper Jack cheese, until cheese melts and mixture is creamy, 1 to 2 minutes. Top evenly with remaining ½ cup pepper Jack cheese.

Step 5

Broil until cheese is lightly browned in spots, about 3 minutes. Remove from oven, and garnish with cilantro.
