Start by marinating the steak with all of the ingredients listed above minus onions & peppers. Make sure its all covered! In a large bowl or a plastic baggie. Let sit on counter while chopping veggies.
Chop onion, and peppers. Place in a hot skillet with a little bit of oil. Season with salt, pepper, garlic powder, chili powder, cumin, and oregano. Let get nice and cooked down & caramelized
Once grill is nice and hot, place steak directly in the center and sear for about 3 minutes. Flip and repeat! Don't move it!
Once steak is nice and seared and done to your liking, remove it from the grill and let rest for about 10 minutes.
Cut against the grain. Serve with veggies, tortillas and all the fixings!
