Well if I try to make this, as I probably will since I'm interested in trying something new and I'm bored with most of my recipes, I don't have pepperoni. I also don't have milk. But it's easier to buy milk than pepperoni. Making a stromboli does sound good too.
I can go to 7-11 and get milk at any time of the night. If I wanted to buy pepperoni, I'd need to wait for a store that sells decent pepperoni to open. And I can't remember the last time I bought pepperoni. I have ground chicken breast. And I finished spicy turkey sausage last week.
