Fabulous Fajitas!

I've been eating more Mexican food lately.  This started because my friend Nick and I went to El Perico, a local Mexican restaurant that is unbelievably good.  With this food in mind, I decided to try my hand at some beef fajitas.  For a first run at this, I think they turned out great! 

First I made a marinade.  I did this 2 nights ago.  I had only intended to let the steak marinate for 1 night, but it went 2 nights due to a change in our plans.  The marinade was based on this recipe.  I only made 1 minor adjustment.  I added cilantro.  Here's the marinade recipe:

Ingredients:
1/4 cup lime juice
1/3 cup water
4 cloves minced garlic
2 TBSP Olive Oil
2 tsp Soy Sauce
1 tsp salt
1/2 tsp liquid smoke (hickory)
1/2 tsp black pepper
1/2 tsp cayenne pepper
1/2 tsp dried cilantro

Directions:
Combine all ingredients in a plastic bag.  Place desired meat in the bag and refrigerate for 2 hours to overnight.

Okay, I used flank steak for the meat.  I had a 1.2 lb flank steak and it marinated for almost 2 days.  I'm sure 24 hours would have been plenty.  Here's what I did tonight to assemble the fajitas.

Ingredients:
1-1.5 lb Marinated Flank Steak (using marinade above)
1 red bell pepper, sliced
1 green bell pepper, sliced
1 yellow onion, sliced
2-3 TBSP Fajita Marinade
1 TBSP Olive Oil
1/4 tsp salt
Southwest seasoning to taste
10 - 6 inch flour tortillas

Directions:
1 - Remove the steak from the marinade, wiping off the excess.  Grill or Broil to a medium doneness.  Let rest for 10 minutes before slicing.
2 - While steak is resting, add reserved marinade and olive oil to a hot cast iron skillet.  Once the oil and marinade sizzling, add the vegetables and salt and stir fry for 10 minutes.  For additional spice, add southwest seasoning at this point.
3 - Slice the steak, across the grain, into 1/4 to 1/2 inch thick strips.  Add the strips to the skillet and stir fry for an additional 2 minutes.
4 - Place the tortillas on a microwave safe plate, cover them with a towel and microwave for 45 seconds. 
5 - Serve fajita beef and vegetable mixture with tortillas.  Add refried beans and cheddar cheese on the side if you want.

This was SOOOOO good.  I did add some southwest seasoning.  I liked the extra kick, but I think next time I'll leave it off so the marinade comes through even more.  The marinade is unbelievably good.  I loved this dish and can't wait to make it again!
