High-quality, organic, dark chocolate is a not-too-sweet treat that satisfies the desire for something sweet without derailing all your hard work. Look for bars that are at least 70 percent cacao, and then break them into bite-size pieces, place on a beautiful serving dish with a few dry roasted nuts and a few unsweetened coconut flakes, and relish how no one complains that they're denied a gloppy, over-the-top dessert.
