Preheat oven to 400°F. Line a large baking sheet with foil and lightly spray with cooking spray. Set aside.
Combine cooked shredded chicken, cream cheese, shredded cheese, diced green chilies, black beans, chipotle salsa, and chopped cilantro. Mix and set aside.
Place one tortilla on your work surface (cutting board, counter, ect.), and place 2-3 tablespoons on the tortilla. Roll the taquito and place on the prepared baking sheet, seam side down. Repeat with remaining tortillas.
Brush taquitos with a little oil and bake for 15-17 minutes. The top and edges should be crispy and browned.
While the taquitos bake it is time to make the sauce. To make the dipping sauce, use ⅔ cup Ranch and ¼ cup chipotle salsa. Mix together and set aside till you are ready to serve.
Remove taquitos from the oven and serve on a plate. Drizzle with the creamy chipotle ranch or serve on the side for dipping.
