>> I have to bring spaghetti and meatballs (pasta separate from sauce +
>> meatballs) to a dinner at my son's school tomorrow night.

That is a risky dish....I am positive that some child will have a
gluten reaction.....a tomato reaction....a dairy reaction.....an
oregano reaction....a mushroom reaction.....an oil in the water
reaction......a salt reaction.....a green pepper reaction......a parm
cheese reaction......a garlic reaction.

I would take boiled water and label the contents with the water
chemistry warnings: Consume at your own risk....boiled water was used
in the preparation of this dish.
