Move over baked beans, because Boston is about to become the East Coast mecca for vegan pizza. Peace O’Pie, which opens today in Allston’s Union Square, is a vegan-owned and -operated gourmet pizza bistro. The impressive menu boasts a bevy of tasty eats, including cheesy Daiya breadsticks and on-the-go calzones. The menu’s main attraction is the mouthwatering selection of pizza options. Pies can be made with classic Vegan Gourmet cheese or stretchy, gooey, Daiya cheese on an organic, whole-wheat or gluten-free crust. Try the EP pizza, made with smoked tempeh, sun-dried tomatoes, sautéed spinach, and garlic. For more creative types, opt to build your own pizza with yummy toppings like apple-sage sausage. Be sure to grab a banana pumpkin cupcake on the way out—or on the way in next time.
