Thinly slice the steaks (it is always easier after they have been in the freezer for a bit). Season the steak with worcestershire sauce, steak seasoning and taco seasoning.
In a large skillet over high heat saute the steak until desired doneness. Remove meat and set aside.
In same skillet over high heat cook sliced onions until cooked through about 3-5 minutes. Remove and do the same with peppers.
For meal prep, add portions of meat, onions, peppers, beans, rice, cilantro, tomatoes to each containers. Option to add shredded cheese and salsa as well.
