This recipe tastes delicious and is so quick and easy! I needed to make 5 hoagies and was not planning on making enough for leftovers so I decided to use 25 meatballs instead. I cooked 25 frozen italian meatballs in my 2 qt slow cooker for 4 hours on LOW. (I have the 3 in 1 cooker) My LOW setting really cooks on low heat but if you decide to adjust the quantity be careful that your sauce doesn't scorch. I eliminated the onion, used traditional Ragu sauce with my own seasonings added in, and sliced mozzarella cheese to go on top. I used 5 meatballs for each toasted sandwich and sliced the meatballs in half, lining each side to make it easier to eat. Top with some extra sauce and broil to melt the cheese. This made 5 hearty sandwiches. I made this with fresh sub buns from the bakery. A new favorite in our house!

I make these all the time for my family. I follow your recipe other then I don't add the onion. We use provolone cheese. My boys love these. I take these to the go kart track and the boys say I make the best meatball sandwiches :)
