Sandwiches may be considered a lunchtime favorite, but they’re far too tasty and satisfying to be enjoyed at only one time of day.

So, stuffing saucy meatballs leftover from this classic spaghetti and meatballs dinner into crusty rolls and turning them into warm, cheesy subs is a wise decision, indeed.
