I find grocery roisterrie chickens too small to feed a large family. What I do (although I haven't done at Disney since we usually eat dinner out there but for our other timeshare stay) is to marinate chicken and then, grill it. I usually marinate enough to make leftover meals. For example, the first night might be grilled chicken, pasta and a vegetable. Then, for lunch I will make ceasar salad with grilled chicken and then, for another dinner I would make chicken quesidillas with refried beans and cucumber/avocado salad. What ever I make I make sure the ingredients rollover into other meals. I do bring my spices with me. I've been known to bring ziploc baggies of premixed pancake mix (my kids don't like the stuff from the box). I bring all my spices in tupperware containters.
Here's my recipe for the marinated chicken:
3/4 cup fresh lime juice
6 garlic cloves, minced
2 tsp salt
2 tsp dried oregano
1 tsp ground cumin
1 bay leaf, crumbled
1/2 tsp ground pepper
3 lbs skinless, boneless chicken breast (you can for faster prep get the chicken cutlets)
Combine lime juice, garlic cloves, salt, oregano, cumin, bay leave and pepper in a large zip lock bag. Add the chicken and marinate no more than one hour. Grill as usual or bake in the oven. We prefer the grill method.
This is great chicken and tastes yummy.
I also have a steak fajita recipe that I do the same with and I'll make fajitas the 1st night, quesidillas the second night, steak salad for lunch, or even eggs and steak for breakfast.
So, even though I love to cook I just make sure that when I cook on vacation that one meal can be made into at least 2 more meals.
