Organic vegetables are grown without the use of pesticides, as they naturally repel pests by repeating everything they say in a sing-song voice. Savor the taste of these wonder foods with today's Groupon: for $15, you get $30 worth of organically sourced gourmet pizzas, sandwiches, and pasta at Stone Hearth Pizza. This Groupon is valid at the restaurant's three locations in Belmont, Needham, and Cambridge, and can be used in the Allston location after its opening at the end of September. This Groupon is valid for both dine-in and carryout.

Stone Hearth Pizza's oven-fired Neapolitan-style pizzas meld only sustainable and locally sourced organic ingredients in an open-flame oven and have helped the restaurant earn accolades from publications including Boston Magazine and The Boston Globe. The menu brims with a selection of thin-crust pies, including the four cheese’s melty mélange of mozzarella, fontina, parmesan, and goat cheeses ($7.95+). A quartet of gluten-free pizzas ($5.60+) delight wheat-averse patrons and farmers haunted by mutinous barley uprisings. Diners craft blueprints for their own pie ($8.25 for a 12"), drawing upon organic tomato sauce or garlic-infused olive oil to serve as a foundation for fresh proteins, cheeses, and veggies that include yukon gold potatoes, caramelized onions, and eggplant ($.75+). Fluffy flatbread sandwiches include the Stop, Chop, & Roll, in which balsamic dressing conducts a mellifluous orchestra of fresh veggies, chicken, bacon, and blue cheese ($6.75). Emerging from kitchens escorted by homemade organic bread, an aromatic array of penne rigate pastas ($9.50+) harmoniously coast onto palates.

Stone Hearth’s skilled staff hand-forms dough in an open kitchen, allowing diners luxuriating in the sun-soaked dining area to discern the chef’s culinary secrets without hiding inside a dessert cart. Though not included in today’s deal, Stone Hearth also irrigates parched patrons with a regional beer list and globetrotting array of wines.
