foreach (var pizza2 in pizzas)
{
    if (selection <= FoodMenu.pizzas.Count)
    {
        string temp = pizza2.ToString();
        string name = temp.Substring(0, temp.IndexOf(","));
        string toppings = temp.Substring(name.Length, );
        int price = int.Parse((""));
        Pizza pizza = new Pizza(name, toppings, price);
