it may well be better to allow that one to be entered and to attempt to receive votes.. rather than completely leaving such a submission out of the contest...
If it's a pizza contest and someone submits an entry that is clearly not a pizza, what's the point then? If next year we make a pasta contest would you ever submit a risotto or a salad?
I'm sorry but are we actually debating what is considered pizza in 2023? Just a quick copy-paste from Wikipedia:
Pizza is a dish of Italian origin consisting of a usually round, flat base of leavened wheat-based dough topped with tomatoes, cheese, and often various other ingredients, which is then baked at a high temperature, traditionally in a wood-fired oven. [

If the "pizza" is not baked of course it can't be considered a pizza. If someone uses cake ingredients it can't be considered a pizza. I'm not saying that all the pizzas must be exactly as stated above but at least some basic steps must be followed.
