 It's now grilling season in Canada so I'm going to show you how to make my favorite Portobello mushroom pizzas. I'm starting with brushing olive oil on the Portobello mushroom caps and putting them on the grill for three to four minutes each side until they're browned. I'm then adding some of my favorite pizza sauce inside the Portobello mushrooms along with sautéed spinach, garlic, and topping them with my favorite vegan feta. Don't they look fantastic? I'm then placing them back on the grill for about 12 minutes or so. I'm making flatbread pizzas with the Portobello mushrooms on top at the same time by the way and I'm just adding this covering over it so the cheese melts pretty quickly and there you go.
