in a saucepan add in sauce, meatballs and spices. if using onion you can peel rince and dice and add in. you can also add in mushrooms if you want

if you prefer like I did I sliced my mushrooms and fried them in old bay , garlic and butter

let the meatballs simmer on about medium for 20 to 30 mins stirring often

turn the heat down to low and let simmer a little longer still checking and stirring occasionally

if you want to toast the sub roll do so in the oven

when the meatballs are fully hot in the middle get your rolls onto plates

take the meatballs and sauce and cover the cheese. the cheese will melt.

add any topping or condiment or none. your choice.

serve hot and enjoy
