These are pretty fabulous not only because they are tasty but because they could not be easier to make. I've waited 13 years to share these with the world and I couldn't be more excited. —Gwen simplyhealthyfamily
Throw chicken breasts into a hot pressure cooker, secure lid and bring to 2nd ring. Reduce heat to low and cook 10 minutes if frozen, 7 if thawed. Let pressure come down by removing from heat. Boil chicken for 15-18 minutes if you don't have a pressure cooker. Remove chicken breasts and place in a Kitchen Aide Mixer (or similar) with the cookie dough attachment. (see my post here on this neat little trick on how to shred chicken in 30 seconds).
Pour chicken broth from pressure cooker into a bowl and set aside. Wipe out the pot with a paper towel and return to medium-high heat. Add 3 tablespoons oil to pot, let heat for a few minutes then add chopped onion. Cook for 5 minutes until golden brown and translucent. Add shredded chicken to pot and toss to coat. Let sit for 5 minutes, toss and cook a few minutes more. Pour in El Pato chile sauce and toss to coat. Cook a few minutes till heated through.
Meanwhile, in a small sauce pot, heat 1/2 of the oil over medium high heat. Using tongs and a fork, carefully place tortillas, one at a time into the pot of oil. Using the tong and fork shape them into tacos. Remove from oil when golden brown and crispy. Place on a pile of paper towels to drain. Scoop chicken into taco shells, garnish as you please.
