1 to 2 Tbs olive oil
1lb sirloin steak, trimmed
salt and pepper to season
1 large white onion, sliced
1 tsp dried oregano
2 garlic cloves, minced
8 oz sliced mushrooms
1 poblano pepper, seeded and sliced
fresh salsa/pico de gallo (optional for garnish)
shredded cheese (optional for garnish)
cilantro, chopped (optional for garnish)
scallions, chopped (optional for garnish)
Heat 1 Tbs oil in large skillet over med-high heat. Season steak with salt and pepper. Add steak to pan and cook about 5 minutes on each side. Remove from pan and set aside. Add remaining oil, if needed, to pan. Add onion, oregano, garlic, mushrooms and poblano pepper to pan. Sauté for about 5 minutes or until vegetables begin to soften. Meanwhile, cut the steak against the grain into thin slices. Add steak back to pan and sauté for one minute more. Taste for seasonings.
Add steak/veggie mixture into warmed corn tortillas and serve with salsa, cheese, cilantro and scallions! Don't forget that tacos are perfect with an icy cold beverage. I happen to find great delight in Colorado's New Planet Beer. It's refreshing and even tastes like "real" beer!
