My dad used to make pizza subs for me when I was a kid. It’s really simple. All the ingredients needed are, hot dog buns, pepperoni, tomato cause and cheese. Slop everything on like you would do on a pizza, bake it for 5 minutes and VOILà! But obviously the flavour has changed from when I was younger to now, and my dad used the exact same ingredients too! It’s weird how things change over time.
