Steak and Potato Tacos with Poblano Chilies

Step 1
Heat 1/2 tablespoon oil in heavy large non-stick skillet over medium-high heat. Add onion and chilies and saute until tender, about 10 minutes. Transfer onion mixture to bowl (do not wash skillet). Heat 1 tablespoon oil in same skillet over medium-high heat. Add potatoes and saute until golden brown and tender, about 12 minutes. Return onion mixture to skillet with potatoes and keep warm.

Step 2
Meanwhile, sprinkle both sides of steak generously with garlic powder, chili powder, salt and pepper. Heat remaining 1/2 tablespoon oil in heavy large skillet over medium-high heat. Add steak and cook until browned on both sides, turning once, about 8 minutes total for medium-rare. Transfer steak to cutting board; let rest 5 minutes.

Step 3
While steak rests, heat tortillas on griddle or over gas flame until warm, turning frequently with tongs.

Step 4
Thinly slice steak. Top tortillas with steak and potato mixture; sprinkle with cilantro. Serve passing pico de gallo and/or hot sauce separately.
