Begin by slicing the steak into thin slices for the fajitas. After slicing this continue by slicing the peppers and onions.
In a cast iron skillet, pour a little bit of oil in and let it warm up. Next, toss in the steak and the Worcestershire sauce. Let this cook until well done.
Once the steak is done, add in the veggies until they are soft. Be sure to watch the heat at this point so that the steak does not overcook. I usually go down to low to medium heat.
Once this mixture is done place on warm tortillas and serve with a side of corn salsa.
