These aren't spectacularly creative but it's what I've got:

(1) After Thanksgiving, virtually everyone will turn their leftover turkey into something, such as sandwiches, or just eat the leftover's like yesterday's meal. For me, I have saved the neck (instead of throwing it out)and the carcass and boiled to create a stock; then combined with standard soup ingredients to make quite the amazing turkey soup. The process involves searing the neck if you want to be iron chef like. The last time I did this was maybe Thanksgiving of a year ago. I skipped it for the recent holiday.
(2) We usually pack fruit for lunch or for snacks around the house. But, near the end of the week, for a healthy choice we would take the fruit, some squeezed lemon/dijon mustard dressing mixture that we make, parm cheese sprinkle and tomatoes and arugula to create a dinner salad. Typically a melon such as watermelon works very well and the combination of everything makes for a bright salad. We've done it so many times it has converted from a frequent leftover into an intentional meal when we grocery shop.
