3 pounds skirt steak or boneless chicken
1/4 pound mushrooms, sliced
1 large onion, sliced into half-moon strips
1 teaspoon olive oil
1. Cut steak or chicken across the grain into strips 1/2 inch wide and 2 inches long. The slices should be sliced as uniformly as possible for even cooking, and no thicker than 1/8 inch. It may be easier to do this with partially frozen meat.
2. Place the meat in a bowl and pour the marinade over it. Toss so that it covers the meat evenly. Cover and marinate for 1 hour in the refrigerator.
3. Add the mushrooms and onions. Mix well, cover and refrigerate 1 hour more.
4. Pour the meat, mushrooms, and onions through a sieve or colander into a bowl, reserving all excess marinade. Put the marinade in a saucepan and bring it to a boil. Keep it hot until serving time.
5. Over a high flame or setting, heat a fajita pan (flat, oblong skillet), or a cast-iron frying pan until very hot. Add the olive oil and spread to coat the pan (if your pan is small, divide the mixture and use 2 pans). Add the meat mixture and stir fry for about 3 minutes, or until all the meat is cooked and tender. Remove from the heat.
6. Set a hot pad or trivet on the table and place the fajitas pan on it. The meat is customarily wrapped in warm flour tortillas and served with any of the following: rice, refried beans, salsa, fresca (chopped tomato, green chiles, onion, lemon juice, salt, and pepper), green or red salsa, sour cream, grated cheddar cheese, guacamole or sliced avocado. Serve the hot marinade in a pitcher on the side.
