Using a sandwich maker makes it easier when you are making these wraps, but it's absolutely not necessary. If you don't have one, it is no big deal. You can easily make this chicken avocado wrap in a skillet. I like to butter the outsides of the wrap and them place it in a heated skillet. This will give you that golden brown outside. Flip the wrap over and grill the other side. If you like the smashed look, you can place a heavy cast-iron skillet on top of the wrap.
