And cut the pepper into thin strips of ¼ inch in thickness.
In a mixing bowl, add the pepper strips, olive oil, apple cider vinegar, red pepper flakes, and salt.
And toss until the seasonings coat the pepper strips evenly.
And bake for about 20 minutes or until the edges shrink and turn golden brown.
Serve as a topping for burger, or in the taco.
