"This is my "signature" dish. Always get raves on them. They are a bit time consuming, especially if you decide to make your own Pico de Gallo and Guacamole, but well worth it. I sip on a margarita to make the experience most authentic! * I find that I barely have enough cream sauce, you might consider doubling it for ease. * Here is a recommendation for the order of prepping things... *Start chiles soaking (30 minutes) *Cook chicken (I just boil chicken thighs in chicken stock...they need to cool before you can shred the meat) *Drink Margarita *Butter 13x9x2 baking dish *Preheat oven to 350°F *Slice and sauté mushrooms *Drink Margarita *Make sauce *Make filling *Assemble *Cook and eat (and drink Margarita)!..."
