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 American comfort cuisine at The Brown Bag Deli on Fred Wilson Avenue.

Voted best sandwich/sub in the Best of the Border contest by El Paso Times, The Brown Bag Deli features a gargantuan selection of award winners, including 30 different combinations, like the pastrami, corned beef & cheese ($5.79 for large) and the turkey & avocado ($5.89 for large) or the choice to build your own meat and cheese house with bread walls. In addition to its signature fare, the deli provides an array of salads, bagels, and baked goods. For a whimsical conclusion, side the feast with a fountain drink ($1.29 for 32 oz.), throw a penny into it, and make a wish for another fountain drink that doesn't have a dirty penny in it.
