Crock pot meals??? Haven't ever seen a crock pot in a TS.
We were at a TS for Christmas, which led to the cooking of a turkey and stuffing which gave us several days of quick and easy follow-up meals from the leftovers (sandwiches, hot turkey and gravy (from a package), etc.). It was kind of a stay-at-home day, not likely to happen at WDW, tho. But one day of cooking made for easy meals for several days.
Lots of easy to fix things are great -- jarred spaghetti sauce with frozen (turkey or other) meatballs; shrimp and bagged salad, chicken baked with BBQ sauce, etc. We have a car and make a grocery run (and haul stuff along in a cooler). Go for simple, using some prepared things that are not loaded with bad stuff. The prepared bags of salad stuff (lettuces, shredded carrots, spinach, broccoli slaw) are wonderful when traveling -- add some shrimp, or leftovers from a store-bought roasted chicken.
(I don't live to eat, I just eat to live -- so simple non-gourmet works for me. I don't do much in the way of ADR's either -- too restrictive, and too much [expensive] food).
I may have to think about taking along a crock pot, tho -- that sounds handy. (altho getting it ready to go might interfere with getting to rope drop -- or not, mine has a separate bowl, so I could load it up the night before!).
