Something is a spicy-pizza if-and-only-if-it is a pizza and has-topping a spicy-topping.
Something is a vegetarian-pizza if-and-only-if-it is a pizza and is not a thing that has-topping a fish-topping and is not a thing that has-topping a meat-topping.Every four-seasons has-topping nothing-but things that are anchovies-toppings and-or are caper-toppings and-or are mozzarella-toppings and-or are mushroom-toppings and-or are olive-toppings and-or are peperoni-sausage-toppings and-or are tomato-toppings.
