There's a new kind of burger called the "Blend." It a real burger. Whatever kind of beef you want blended with mushrooms. Supposedly, it tastes like a real burger but it's much healthier for you.
This idea seems to be catching on at restaurants across the country. Even fast food giant Sonic is experimenting with their version of a blended burger.
I don't like mushrooms. We've had mushroom burgers on restaurant menus for years. If you blend in the mushrooms just right the burgers might look and taste the same. I would be fine with that if the price of the burger was the same. When in doubt, any burger can be made better with an extra slice of cheese!
