To prepare taquitos, heat oil in a large nonstick skillet over medium heat. Add chicken, and sauté 5 minutes or until done. Place chicken in a food processor. Add cheese, beans, and green chiles; pulse 15 times or until beans are coarsely chopped.
Spoon about 3 tablespoons chicken mixture across the lower third of each tortilla; roll up. Cut each tortilla in half; secure with wooden picks. Place taquitos in a large zip-top plastic bag; freeze up to 3 months.
Preheat oven to 400º.
Place frozen taquitos on a large baking sheet coated with cooking spray. Bake at 400° for 10 minutes; turn taquitos, and coat with cooking spray. Bake an additional 10 minutes or until golden.
To prepare adobo sour cream, combine sour cream, cilantro, and chipotle chile. Stir well.
