Game Day Burgers: Vegetarian Portobello Mini Sliders

If you haven’t figured it out yet, our staff is rather divided when it comes to game day delights.

Some of us prefer to live the carnivorous life, devouring every bit of beef and chicken (wing) in our path, and the rest of us want to eat something delicious, but (still) a bit more figure conscious. As a compromise, we turn to the mighty mushroom!

High in calcium and Vitamin D, mushrooms provide many of the nutritional attributes of produce and other fresh vegetables, as well as attributes more commonly found in meat, beans or grains.  Mushrooms are low in calories, fat-free, cholesterol-free and very low in sodium, yet they provide several nutrients that are typically found in animal foods or grains.

This game day burgers recipe satisfies meat and vegetable lovers with it’s thick, juicy grilled flavor, and savory sweetness from the balsamic vinegar in this recipe.
