Starting out, preheat oven to 425°F.
In large bowl, add cut peppers and onions, ½ the amount of olive oil and ½ the amount of seasoning.
Next, add in the steak, the remaining ½ of olive oil and the remaining ½ of seasoning then mix everything together. Make sure everything is coated well.
Dump the bowl of mixture onto a sheet pan and spread it out flat.
Bake in oven for 10-15 minutes. When that is done, if you want extra char, put the tray under the broil for 2 minutes.
Let the food cool for a couple minutes before serving (can be used to make tacos, quesadillas, over rice, or just placed in a meal prep container for a later easy meal)
