Sure, let's break it down:

- "Half of the pizza... for you and half... for me."
- "Half of the pizzas... vegetarian."

So, if we have one pizza, we can split it equally between us. If we have multiple pizzas, we can ensure that half of them are vegetarian.

For example, if we have 4 pizzas:
- 2 pizzas will be vegetarian.
- The other 2 pizzas can be any other type.

This way, we can cater to different dietary preferences.
