1. Preheat your oven to 400 degrees and place your onion, peppers and steak on a large sheet pan.
2. Stir together the chili powder, cumin, garlic powder and salt in a small
bowl. Drizzle everything with olive oil, followed by the spice mixture. Use your
hands to toss until evenly coated.
3. Bake in the oven for 10-12 until steak is browned and just cooked through.
Serve with fresh cilantro and lettuce wraps.
