This is one of my favorite dinners. It’s easy since most everything can be prepared ahead of time, like dry rubbing the steak, the peppers and onions and even the crema. Most of all, I just love these flavors. The sweet, spicy and smokey flavor of the chipotle is wonderful with the richness of the avocado crema. Skirt steak is perfect for fajitas. It’s rich in flavor and when cooked properly and sliced thinly it becomes more tender and very satisfying.
