Smokey Mesquite Grilled Chicken Sandwiches

I made these one night, last minute, with some bread my mom brought over that I had never tried before and some chicken I threw on the griddle. It turned out fantastic and Shawn loved it so I thought I'd share!

Ingredients:
- Smokey Mesquite seasoning (from Costco, I'm sure they have it other places too)
- 100% Whole Wheat Sandwich Thins (in bread isle made by Oroweat...100 calories!)
- Chicken breasts or tenderloins, if using breasts, split them up the middle so they're thinner.
- Butter (to butter bread)
- Cheese (any)
- Mayo & Mustard (optional)
- Lettuce, Onions, Tomatoes, Pickles...whatever you like on you sandwich (I love everything, Shawn likes just meat, cheese n' bread)

Directions:
If using chicken breasts, split them up the middle so they're thinner. Sprinkle w/ salt and generously with Smokey Mesquite seasoning. Grill in a pan or on a grill until caramely brown on both sides and cooked through. Meanwhile, lightly butter both sides of your sandwich thins. Remove cooked chicken, scrape pan clean, and then place buttered side down on grill. Flip when golden brown, turn off pan but leave on hot surface. Cover both sides of grilled side of sandwich thins with a thin layer of cheese and allow to melt. Remove from heat, spread w/ mayo n' mustard, add chicken and whatever else you like.
