Thick, pillowy dough; oozing, melty cheese; earthy sautéed mushrooms and onions — this is the stuff of a mouthwatering Mellow Mushroom pizza. The one that's best, however, isn't your average pie; it's a veganized version of the spot's popular Holy Shiitake. Like many of the eatery's specialty pizzas, the HS can be altered for vegans. Skip the aioli, leave off the butter, and switch out the regular cheeses for Daiya and — voila! — you're in pizza heaven. Though not a vegan establishment, Mellow Mushroom goes out of its way for plant-based eaters. The kitchen staff stocks the nondairy Daiya, tempeh, tofu, and fruits and veggies in every color and flavor. Guests can even build their own creations. Beginning with the dough, the pizza masters slather each pie with Daiya ($1.50 extra on a small pie, $2.50 on a medium, and $3.50 on a large). Then they pair pineapple with jalapeños, artichoke hearts with sun-dried tomatoes, broccoli with tempeh — the sky's the limit. And it all tastes just as delicious as the meaty alternatives. Traditional pizzerias, eat your hearts out (but not really, because vegans believe in nonviolence).
