For breakfast we usually just eat bagels and English muffins. We'll also cook eggs and pre-cooked sausage or bacon that's quick to warm up. We make a pot of coffee and take the extra with us to the park in the disposable cups we brought with us (DVC provides some, but not enough). Sometimes we eat some natural-type cereal (like Kashi) with a container of flavored greek yogurt.
We usually eat lunch at CS restaurants. When my DD was little we would bring pb&js into the parks for her. I packed them in Tupperware Sandwich Keepers so they wouldn't get crushed. For park snacks, we go to Costco or Trader Joes to get trail mix and other fruit/nut snack things and I take it out of the big bag and put in into smaller snack bags.
As for dinner, microwavable veggie bags are your friend. Bring spices from home in snack sized ziplock bags. I would plan your meals in advance but I don't think I would make them all crockpot meals. It's probably just me, but it all tastes the same after a while. There are also great places nearby for takeout pizza. We like Giordano's for Chicago stuffed pizza and Flippers for thinner crust pizza. Bring extra dishwasher nuggets from home since I think you are only provided one load's worth.
We also keep snacks in the room like cheese and crackers, chips, fruit, finger veggies, dip, etc. We usually go back to our resort for a swim, snack and rest. We also have the fridge stocked with adult beverages. We have even been known to make blended drinks since you can get a blender at DVC resorts. We'll bring the alcohol in our luggage backed in Rum Runner flasks:

One thing to consider is that unless you have a Grand Villa no one unit will have enough plates/etc to eat off of for 11 teens/adults. You may want to have people bring the plates, utensils, and glasses from their room into the main villa where meals are prepared. Or, you can use disposable plates/etc.
