This is the best grilled vegetable recipe! Zucchini, mushrooms, bell peppers, tomatoes, and red onions are all tossed in a tangy rosemary marinade and grilled until perfectly tender. Whether using skewers, a grill mat or basket they turn out perfect every time! #spendwithpennies #grilledvegetables #sidedish #barbecue #grilling #summer #veggies
