RemovePizza endpoint not working correctly

[SeriesOfTubez]

When calling the RemovePizza endpoint, it's deleting all pizzas EXCEPT for the Id passed to the endpoint. It should be deleting only the pizza that matches the Id. I couldn't find anything obvious, but I'm a noob.

    public static void RemovePizza(int id)
    {
        _pizzas = _pizzas.FindAll(pizza => pizza.Id == id).ToList();
    }

In Swagger:

• Tested the Delete method
• Typed in a pizza Id
• Executed
• Then ran the Get method to list all Pizzas
• All pizzas are now gone except for the one matching the Id passed to the DELETE method

If _pizzas is a List<T>, why not use List<T>.RemoveAll(Predicate<T>) instead of the expensing LINQ operator (ToList())?
