Grilled Portobello burgers are popping up on menus everywhere, but none of them can hold a candle to this marinated version boasting a culinary treasure trove of ingredients – balsamic vinegar, vermouth, Old Bay, soy sauce, and chiles, to name a few. The only thing that can possibly make this burger better is its sidekick of a Belgian Ale, American Wheat Ale, or American or English Pale Ale. And that’s before you even hit up the potential variations that follow, including a Portobello Fire Burger, Buffalo-Style Portobello Burger, and Sauerkraut & Portobello Burger.
