Avocado Salad-Topped Steak Tacos

1/4 cup extra-virgin olive oil
1 1/2 teaspoons chili powder
1 pound skirt steak, halved crosswise (or whatever you have)
Salt and Pepper
2 jalapeno chiles, finely chopped
Grated peel and juice of 2 limes
1 head butter lettuce, shredded
2 avocados-halved, pitted and cut into small cubes
1/2 onion, thinly sliced
12 taco shells

Preheat a grill pan over medium-high heat. Whisk together 1 tbsp olive oil and the chili powder, then rub all over the steak; season with salt and pepper. Add to the grill pan and cook turning once, until grill marks appear, about 5 minutes for medium-rare. Transfer to a cutting board and let rest for 10 minutes before thinly slicing across the grain.

Meanwhile, in a medium bowl, combine the jalapenos, lime peel, lime juice and remaining 3 tablespoons of olive oil; season with salt and pepper. Add the lettuce, avocados and onion and toss; season with salt and pepper.

Divide half of the avocado salad among the taco shells, then top with the meat and the remaining avocado salad.

**We just cubed steak and sauteed it in the spice mixture (for simplicity). We also added a bit of cheese because they seemed naked without it. The onion was on the side to add as each person chooses. They were SO, SO GOOD!
