Hand-rolled meatballs anchor this sub, nestled in a toasted hoagie roll with melted provolone and marinara sauce simmered from fresh tomatoes. The meatballs stand out for their tender texture achieved through careful rolling and seasoning with herbs and garlic. Provolone melts into every crevice, balancing the richness with tangy sauce. Gluten-free options make it accessible without sacrificing flavor.
