I mean there's dessert pizza, so why not make a breakfast pizza?
Maybe there could be a way to make like a pancake "crust" and then use eggs bacon or sausage for your protein, fruits instead of veggies (except maybe green onions), whatever cheese you want. Personally I'd probably go with cheddar, or a cheddar/mozz mix.
I thought that as well until I ordered overpriced (40€) Dominos pizza on an airport hotel in Narita becuase I was dying from hunger and I had to throw half of it away because of how bad it was.
Tacos, a Welsh wagyu cheese burger, Japanese kobe beef ribs, BBQ ribs, hot bowl korean Bibimbap, deep fried tofu yakisoba, 4 cheese maccaroni and cheese, honey and maple glazed ham egg sandwiches, a really good monte Cristo sandwhich, beneficial salmon benedict or even regular eggs Benedict... should I keep going?
I really like pizza, and there are some great ones out there. But in a world of choices it's still just pizza.
Unfortunately vegan pizza isn't the same. It's one of the foods that's not quite the same without real cheese. So I mostly abstain, sometimes I try the vegan cheeses but they're not good imo
Calzones are pretty awesome, but it's not quite the same when the toppings are not exposed to the oven to get crisped up / browned as they would on a pizza.
Cheese and pepperoni especially just hit different on a well-cooked pizza!
The best I can think of are actually Italian, Swiss or English dishes co-opted by the French and the rest are extremely average, but French food culture is very good which a lot of people seem to confuse with the actual dishes being good
An office I used to work in had a cafeteria that hired professional chefs. On Fridays, they ran "experiments" on some stations, notably the pizza station. They came up with a bunch of really wacky pizzas; the poutine pizza and chicken & waffle pizza were some of my favorites they made. The Sloppy Joe pizza was the only time I've ever needed a fork and knife for pizza, but somehow wasn't awful.
They did a gumbo pizza one Friday, and it was very confusing. They served it on a big, NY-style slice and used pureed gumbo in place of tomato sauce. It tasted pretty good, but had neither the flavor or consistency of either pizza nor gumbo. Probably would have worked better without cheese, but there's potential in those flavor pairings, IMO.
