Plug in your trusty waffle maker. Set to medium heat (if you can adjust).

Place cheese then lettuce then turkey on one slice of bread. Spread the other slice of bread with mustard. Place bread together.

Spray waffle iron with non-stick cooking spray. Place sandwich on griddle. Slowly press down the top, squishing the sandwich as much as you can. Cook for about 2-5 minutes, depending on your waffle iron and how hot it cooks, etc.

When golden brown and crispy, carefully remove from the griddle and serve right away. Enjoy!
