Hey ScurvyD -
I expect you'll get some input from the larger crowd here shortly ... but I'd offer my .02. I do most of the cooking and provisioning for our crew.

We do our own shopping and generally go with the 'Easy on the Cook' model with half of our dinners ashore. Usually end up having 2-3 lunches ashore as well.

I tend to favor easy breakfasts - yogurt/granola, cereal, etc. over bacon&eggs. Makes the dishes easier to get done when you're about to get underway for the day.

I also have found we tend to snack more throughout the day than having a fixed meal. We always do sundowners with something to snack on. Our last dinner on the boat is always eating up all the leftovers.

We've used Riteway and their delivery service and have had good experiences doing it that way.
HTH
