Preheat oven to 350 degrees
Mix the Italian seasoning into the mayonnaise and prep the onions, tomatoes and lettuce
Generously spread some of the mayo mixture onto the bottom slice of the hoagie bun and then layer on about 3 tomato slices, 3 pieces of onion, and some lettuce.
Next, layer on the delicious meats! For our subs, I added 2 slices of ham, salami and a few pepperonis. Of course no Italian Sub is complete without cheese! I folded 2 pieces of provolone cheese in half and put those on top of the meats. To finish off this yummy sandwich, I added a few pepper rings as well.
Once the sandwiches were assembled, I put 4 subs in each baking dish with the openings facing up and pressed tightly against each other. Put in the oven for about 10 - 15 minutes or until the cheese is melted and the buns are lightly toasted.
