Mini phyllo cups just might be the best thing that ever happened to appetizers. To be honest, apps aren't really my thing; give me a bowl of hummus or salsa and something to dip, and I'm all set. However, every now and then, especially during the holiday season, I like to present my guests with something a bit more, well... polished, and that's when I turn to phyllo cups. I always have a few boxes stashed in the freezer; each box contains fifteen little cups, which means you don't need a lot of filling, and you can make multiple batches without much more effort. These spinach and feta phyllo cups are one-bite treats (or, for the very dainty, two bites), and offer a burst of flavor without a heavy filling. It takes less time to put them together than it takes to preheat the oven. How easy is that?
