Mushrooms, tomatoes, zucchini, onions? The garden-fresh gang’s all here! A luscious cheese spread, garlic and balsamic vinegar beautifully complement the grilled flavor in this totally delish dish. —Taste of Home Test Kitchen
This burger is covered with a few of my favorite things...portobello mushrooms, goat cheese, basil and Mascarpone. These burgers are quite juicy, so serve them with extra napkins.—Lisa Keys, Middlebury, Connecticut
A tasty tomato-olive mixture, melty cheese and smoky grilled mushroom add so much flavor to this recipe one taster called it “one of the best grilled mushroom burgers I’ve had.” For a change, switch another cheese or spinach for the provolone and lettuce. —Tamra Duncan, Lincoln, Arkansas
"I put this combination together one day when trying to serve a side dish other than mushrooms in butter," recalls Susan Jesson of Oro Station, Ontario. "Everyone loves this pleasantly seasoned medley and asks for the recipe."
