Meatball and Mozzarella Paninis are full of tasty homemade meatballs, tomato sauce, and melty mozzarella cheese in a piece of buttery crispy flatbread. It’s the ultimate sandwich for lunch or gameday.

 
A little time goes into making this delicious sandwich, but it is so worth it! The meatballs and tomato sauce can be made ahead of time. They will only improve in flavor. And then the sandwich can be made very quickly.
The meatballs are made with lots of seasonings, including a packet of dry onion soup mix, and they really pack the flavor. They are baked in a 400 degree oven until crispy and cooked through.

 
The sauce ingredients just need to be simmered for 15 minutes. The sauce is flavored with onion, garlic, Italian seasoning, and crushed red pepper flakes. Flatbread makes the perfect envelope to hold the meatballs and sauce, but you could use pita bread.
 
Serve with extra tomato sauce on the side and you have one of the most delicious sandwiches imaginable.
