Depending on where you're from, the term "portable pizza" may conjure up anything from large slices of New York-style pizza folded in half served on paper plates to the microwavable American elementary-school treat, Hot Pockets. While wildly different, both make eating pizza an on-the-go affair. However, these trends are rooted in a centuries-long Italian tradition of pizza-style street food.
Now, calzones are often the less-popular alternative to pizza at Italian-American restaurants. Calzones experienced a brief resurgence about a decade ago due to the much-loved yet awkward character Ben Wyatt in "Parks and Recreation," played by Adam Scott.
