Like the earth, a sandwich is made of layers and gathers its strength from its meaty core, which pushes condiments toward the crust to erupt and bury fingers in deliciousness. Let rivers of mayo magma run with today's Groupon: for $5, you get $10 worth of sandwiches and drinks at Tom's International Deli, located on Millbury Street.

The sandwich samurais at Tom's International Deli slice up a menu of succulent, meat-stuffed treasures founded on Polish, German, Hungarian, and Italian cuisines. Improve hand-mouth coordination with a selection of deli-style piles of corned beef ($4.99), buffalo chicken ($5.49), and a one-two protein punch of turkey and BLT ($5.99). Those looking to thaw brain freezes or warm chilly brain nymphs can fill craniums with hot sandwiches, such as the kielbasa and sauerkraut ($4.99). A selection of Italian-inspired options, including the capicola, Genoa salami, and pepperoni sandwich ($4.99), are sure to conjure up visions of Italy's cheese-capped mountaintops and provincial pizza farms. Tom's also features extradeli amenities such as spices by the ounce and a herring, olive, and pickle bar.
