Preheat the oven to 400°F. No need to grease the silicone muffin pan.
Mix the egg whites with water to thin slightly. Add 1 teaspoon of the egg white mixture to each cavity of the silicone mini muffin pan, just enough to coat the bottom.
Top each with a small amount of cheese.
Bake for 20 minutes or until golden and crispy.
Remove from the oven and let cool for about 5 minutes. The crisps should easily pop out of the silicone mold. Enjoy!
Notes
You will also need a 12 cavity silicone mini muffin pan (I recommend this one – amazon)
