Temper the bitterness of these radish greens by roasting them and the radishes.
Heat oven to 375 degrees.
Separate radishes and their greens and arrange on 2 rimmed baking sheets. Drizzle each with olive oil and season with salt and pepper. Toss to combine.
Bake, until radishes are tender and caramelized and greens are crisp, 15 to 20 minutes. Let cool.
