The original calls for jalapeno powder. If I don't have it in my kitchen, it isn't something that is going to be used often so I left it out. Most of the ingredients will be in a normal kitchen except maybe the Ancho powder. You can sub in whatever chili type powder you have if necessary.
Shelly's Chick'n Taco Seasoning Mix
1 Tbsp Mexican oregano
1 1/4 tsp Spanish paprika
1 1/4 tsp salt
1 tsp cumin
3/4 tsp onion powder
3/4 tsp garlic powder
1/4 tsp cilantro
1/4 tsp ancho chile powder (add an additional 1/8 tsp if you like it spicier)
1/8 tsp black pepper
Blend together with a whisk.
I prefer not to add a bunch of oil to my food so I'd just cook or warm up whatever 'chick'n' I was using, sprinkle the seasoning over it and add in some water and cook it until it's coated and done. Not rocket science. I'd even add a squirt of lime juice if I was feelin' it.
The original recipe give these directions for the equivalent of one pound of chicken. If you're using pre-cooked items then you'll need to adjust the initial chicken cooking time.
In a large pan over medium heat, heat 2 tbsp of corn oil and cook chicken for 7 minutes , Stir in 1 tbsp lime juice and 2 tbsp of the seasoning mix. Cook 2 minutes. Add 1/2 cup water, reduce heat and simmer until done.
