Heat the olive oil in a large skillet over medium high heat.
Add the garlic and red pepper flakes to the skillet and cook until fragrant, about 30 seconds.
Add the radish greens to the skillet and toss. Cook the greens until they are just wilted, about 2-3 minutes.
Remove the skillet from heat and stir in the lemon juice. Season the greens with sea salt and pepper and serve immediately.
