Shape the mixture into approximately 16-20 meatballs, each about 1.5 inches (3.8 cm) in diameter.

Heat olive oil in a large skillet over medium heat. Once hot, add the meatballs in a single layer, working in batches if necessary. Brown on all sides for 5-7 minutes total.

Place 4-5 meatballs inside each toasted roll, spooning extra sauce over them.

Top each sub with ¼ cup shredded cheddar cheese and 2 slices of crispy bacon, broken into pieces if desired.
