I take pitted black olives (less messy) and bung 'em in a baking pan with red wine, sliced garlic, pepper, fennel seeds and red wine. Stick it in a 350 oven for 20 minutes and bake until the aroma drives you wild and you have to taste them. For endive leaves, I've been getting into a jicama, blood orange and avocado salad, that could be spooned into the leaves pretty easily. It's got nice color and crunch, and if you dress the salad with some lime juice and maybe chili oil, the avocado won't discolor and you can keep it chilled in the fridge.
