Grilled Spiced Skirt Steak Tacos

I found a great deal on a skirt steak and lucked upon this recipe when trying to figure out what I wanted to make with it. We loved the flavor of this skirt steak. My son wants me to use this marinade again to make one and not make tacos from it. He says he likes ground beef tacos better but loved the flavor of this steak. I did leave out the cilantro due to hubby and son's dislike. I pan fried ours but it would be great grilled or broiled as suggested in the recipe. The marinade is made from cola, chili powder, cumin, lime juice, chopped onion, and olive oil and the cilantro which I omitted. She also includes a recipe for a fresh salsa within the recipe which was a pretty typical one and quiet good. Hubby and I added to chopped avocado rather sliced in my version to our tacos but since son hates avocados I left that off his. She suggests crisp corn taco shells but we had those and also some soft taco shells. I love the soft shells but though the crisp ones were better with the skirt steak.
