- Cut pepper into 1/4" strips and thinly slice onion. 
- Heat a tablespoon of oil in nonstick skillet on medium-high heat. Add 1/4" strips of pepper and onion and stir to cook through. Cook until soft, about 8 minutes. 
- Add a cup of water and turn heat to high setting. Boil until water is evaporated and veggies are tender, about 4 minutes. Remove from stove, season with salt and pepper and cover so they stay warm. 
- Heat grill/grill pan on medium-high heat. In bowl, combine cumin, garlic, and the rest of the oil to make thin paste. Spread on steak and rub into both sides of meat. 
- Season the steak with salt and pepper, grill 5 minutes each side for medium rare. Remove from heat and allow the steak to rest for 5 minutes. Thinly slice across grain. Serve with peppers and onions. 
- If you do not have poblano peppers available, use a bell pepper with a dash of hot sauce. For extra flavor, allow steak to marinate at room temp for 30 minutes before cooking.
