What other foods would you say are like pepperoni pizza (besides other types of pizza)?

Controversial to some, but you can put the tomato mixture, melted cheese and pepperoni on pretty much any other unsweetened carbohydrate base, and it's nice, and should give you most of that "pepperoni pizza" feeling.

For example, bread, toast, pitta bread, potato cake, potato waffle, pancake, Yorkshire Pudding, pasta, roast potato, baked potato, chips (fries), crisps (chips), noodles, rice etc
