Boiled beets, feta cheese, crisped bacon, and clementine segments are an unexpectedly delicious combination, and are what makes this salad such a standout. Pomegranate seeds up the ante even more, providing even more pops of color and bursts of tartness. Using a mix of greens, including lettuce (your choice), peppery arugula, and tender mache (or lamb's lettuce) makes for a more interesting taste and texture than just one type would.
