I am up 3-4 hours prior to opening.
I am ready for the day before the kids get here. I like to eat with my own kids before they go off to school in the mornings.
I also have occasional "big cook" weekends where I will prepare about 4 chickens, 2 hams, brown a few pounds of ground beef and turkey, cook down several messes of greens and beans then put together a few "rough day" casseroles and stews.
I tend to grab whatever they have a lot of at the local farmers market. It makes for a varied, seasonal diet.
When the freezer stays stocked with starters, veggies and back-ups, food becomes a non-issue. It does require some serious freezer space, I have three.
