We cook about half our meals, but make them quite simple.
Breakfasts-- Eggs/Bacon/toast, bagels/cream cheese/lox
Lunch--Sandwich fixings, Salad
Dinner--Spaghetti or baked ziti, salad, and french bread, Crock pot type meals (chili, chicken chili verde, etc)
Snacks--Fruit, chips, frozen pizza
We cook much simpler than at home. At home, I make salad dressings, bread, make my own sauces, etc. At Disney, we buy dressings, marinara, bread, prepackaged salad and so on. I often prepare food for the next day in the evening if I'm back. My kids are grown, so I expect them to make their own lunches and breakfast unless they're up when I'm cooking.
Btw, the kitchen gear in DVC is not that great, and I imagine it's no better in the Ft Wilderness cabins. We bring some of our own stuff to keep the frustration level down (pizza pan, crock pot, decent knife or two--I have my meal plan in mind and pack accordingly. Or order something cheap from
Amazon. A "disposable" crock pot (for $15-$30) is less than the cost of one Disney meal out, and I'm sure the staff would make use of it if left behind.
