Mr. Donut is a Japanese breakfast fast food chain that uses donuts instead of bread on all of it’s products. According to geek.com, “Mr Donut’s latest creations include baked pies, frankfurter pie and tuna melt toast, but also breakfast sandwiches made with amazing, fresh donuts instead of bagels or bread. The Savory Ham and Egg Sandwich Donut is exactly what it sounds like, with a slice of ham and egg salad inside of a donut.”
