In a large skillet over medium-high heat, warm the olive oil.

Cook the garlic and red pepper flakes in the skillet for 30 seconds or until fragrant.

Radish greens should be added to the skillet and mixed. The greens should be cooked for 2 to 3 minutes, or until barely wilted.

Add the lemon juice after turning off the heat in the skillet. Serve the greens right away after seasoning with sea salt and pepper.
