Boil broccoli rabe in salted water for 2-3 minutes. Drain and set aside.
In a skillet, heat olive oil and add garlic and red pepper flakes. Add broccoli rabe and saute for 5 minutes.
Season with salt and pepper and serve warm.
Notes
Chef's Tip: Don't skip the blanching step - it tames broccoli rabe's natural bitterness before it hits the hot pan. Keto Swap: none needed - naturally keto.
