Grilled Portobello Burger Recipe

"Back over the summer I was sent the book, The Ultimate Beer Lover’s Happy Hour. Any book with Happy Hour is one I want to read!

The Grilled Portobello Burger Recipe is one I can’t wait to try, and they suggest pairing it with an Octoberfest Beer. Yum! Here’s that grilled portobello burger recipe!"
