The crisp sharpness of radish contrasts with rich, salty fresh feta, creamy mayonnaise, and fresh spring greens, accented with fresh ground black pepper and a pinch of salt. Best made with slices of soft but sturdy wheat bread, but feel free to substitute your favorite loaf. You can make these dainty with less filling, or hearty and overstuffed for a sturdy lunch or meatless main dish.
Wash and thinly slice the radishes. Wash and dry the spring mix if needed.
Spread the bread with mayo and sprinkle with freshly ground pepper.
Build your sandwich, feta slices first, then radish slices. Lightly sprinkle the radishes with salt (and more pepper if you want). Next, top with a handful of greens, then the other piece of bread.
Slice the sandwich, secure with frilled picks (if you want), and wrap or serve.
