Spice blend
3 tablespoons cornstarch
2 tablespoons chili powder
1 tablespoon kosher salt
1 tablespoon paprika (for more kick, use hot paprika)
1 teaspoon onion powder
1 teaspoon garlic powder
1 teaspoon sugar
1/2 teaspoon cumin
1/2 teaspoon cayenne pepper
Marinade
2 tablespoons oil
juice from one lime
2 tablespoons spice blend
2 pounds of New York strip steak (skirt steak or sirloin work well too)
2-3 colored peppers of your choice
1 medium onion
1 tablespoon oil
12 flour tortillas
Mix together all ingredients for the spice blend in a bowl. Combine marinade ingredients in a freezer bag, seal and shake to combine. Add the steak and refrigerate for one hour. Slice the peppers and onions and combine in a foil pan with a teaspoon of the spice blend and 1 tablespoon of oil. Sauté over medium-high heat until they begin to soften. Grill the steak over medium high heat until the steak is cooked to medium. Remove steak and vegetables. Slice steak into thin strips against the grain.
Assemble fajitas with steak, vegetables and any other toppings you desire.
The extra seasoning blend can be stored in the freezer for next time.
