Twice as much of the non-food consumables as you think you will need, or as close as you can manage.

For the MREs, I have to echo TRO- take what you have, and order more to replace it. It is a window of negative impact until the replacements get in, but I don't know if there is much option. Supliment with cans and wetpacked ham/tuna/chicken, rice (heavy, but you can treat them like MREs for the short term), and vac packed dehydrateds.
