Ham and egg cups are cute little quiches that can serve as a filling, on the go breakfast; as party appetizers; or as a snack. They are very good warm, at room temperature, and even cold straight out of the fridge (yes I tried!). The big advantage of using ham slices as a "crust" is not just the added flavor, but also reduced risk of sticking to the muffin tin compared with standard egg muffins.
