Cook all the sauce ingredients except the cilantro and chicken bouillon. Sauté the chicken in butter.

When done, place them on a plate lined with a paper towel to absorb excess oil. Once the sauce ingredients are boiling, blend them with the chicken bouillon and cilantro. Set aside.

In a baking dish, spread a layer of sour cream, arrange the rolled tortillas, add another layer of sour cream, then the sauce, and finally the shredded cheese.

Cover with aluminum foil and bake or microwave just until the cheese melts. Enjoy!
