The rule is 4 ounces per person, more or less, depending on the appetites.
Sliced bell peppers, either green or a mixture of colors
Onion, cut into strips, to taste (I usually use three peppers to one onion)
Shredded cheese.. If you want to go strictly authentic, use queso blanco. I like shredded Monterrey Jack/Cheddar blend
Sour Cream
Homemade or bottled salsa
Pico de Gallo
Guacamole
Anything you put on them in a restaurant can be put on 'em at home.. I hate guacamole, but my family loves it, so... in it goes. You are going to put these out in jars, or in Ramekins, so get what your family likes...
Flour tortillas, wrapped in foil.
I put my cast iron fajita skillets into a 300 degree oven while I make the fajitas, so I wrap the tortillas in foil and put them in the oven as soon as I start cooking the chicken.
Marinade
1/4 cup lime juice
1/3 cup water
2 tablespoons olive oil
4 cloves garlic, crushed
2 teaspoons soy sauce
1 teaspoon salt
1/2 teaspoon liquid smoke flavoring
1/2 teaspoon cayenne pepper
1/2 teaspoon ground black pepper
Mix all these ingredients... the lime juice does NOT taste right if you use concentrated juice. It takes 1 to 1 1/2 limes to make that amount of juice, and is well worth it.
Slice one breast per person into strips, place in a gallon bag, pour marinade over this, and place in refrigerator for at least one hour, no more than four... overnight tends to turn this marinade into pure lime juice, and the chicken gets bitter.
Drain the marinade off the chicken, and saute the strips in a cast iron skillet. This just takes a few minutes. Take the chicken out of the pan and pour in the onions and peppers, stirring them until they get hot. Remember, your skillet is hot and will cook the peppers as you present the food, so don't get this part over done.
Once the pepper/onion medley is cooked, lightly salt it, put the chicken or steak on top, and serve on the heated fajita pans, OR serve family style right in the skillet you used to cook the food in.
If you do prep work ahead of time, this meal is less than 15 minutes from fridge to table..
Use any leftovers to make Fajita Chimichangas. The recipe for them, Pico de Gallo, and Homemade Salsa with chips are all on this blog.
This meal is filling, tasty, and everyone can make their fajitas the way THEY like them, with their favorite fillings.
If you wanna go all out, throw some re fried beans, lettuce, etc on a plate, add some Mexican or Spanish rice, and you may never eat Mexican anywhere but home after this.
