In a large dutch oven pan heat oil over medium high heat. Add in onions and saute for 2-3 minutes, or until onions are translucent. Then add in seasonings, black beans, corn, and bay leaf. Mix and saute an additional minute. Once aromatic, add in enchilada sauce, chicken broth, and chicken, taste and add in salt and pepper to desired taste. Lower heat to medium and allow to simmer for 20 minutes.

After twenty minutes, return heat to medium high and stir gently before adding in tortellini and cilantro. Cook tortellini until softened. Once tortellini has softened it is ready to serve, unless you'd like it thicker, for a thicker/creamier soup, add in water and cornstarch mixture, gently mix it in and cook for an additional minute or until thickened, then turn off soup and serve.
