Some of the charter companies have "lists" to prompt /guide you.
1st: come up with meal plan. for instance, breakfast may be cereal, english muffins, bagels, eggs& bacon (usually not all on the same day...
Once you have menu, go thru each one to make sure incidents are there. (cereal + milk, bagel + Cream Cheese/ butter etc) . Coffee with sugar/ sweetener, OJ for breakfast? Hamburgers with condiments, chips, etc.
For those requiring a small amount spices, bring these from home, possibly in small ziplock bag (medication size ??)
Determine how many meals you plan to eat out ( we usually do 2-3 per week ). Depending on base facilities, eating simple meal on board is great after long day of travel (vs taxi ride to/ from restaurant, as some are not safely walkable .
Don't forget things you need to clean with such as dish soap, paper towels, trash bags and bags for the head.
We assign one couple for each night to plan the meals and they can then verify ingredients both before the trip and also once provisions are delivered.
I will try to find one of our previous trip menus and post.
