Although some of us here are on a six-pack by June strategy (after many, many false starts), tomorrow's holiday is threatening to throw a major wrench in our fitness plans. Yes carnivores, it's National Meatball Day! In celebration of America's greatest food fest, MamaMancini is giving away a free, hot MamaMancini’s Meatball and Sunday Sauce sandwich on Sullivan Bakery bread or a dish of MamaMancini’s Meatballs and Sunday Sauce with dipping bread—delivered to your home or office. For the waistline-expanding treat (but so, so worth it) email meatballday@mamamancinis.com, the first 50 to do so will be enjoying tasty balls tomorrow. The delivery service is from 12 p.m. to 3 p.m. on March 9th only, in the Manhattan area. For more deets, click here.
