Step 1

In a large, heavy-bottom skillet, heat olive oil over medium-high heat. Add the red pepper flakes and green beans. Toss together. Cover pan with a lid or sheet of tin-foil and cook for 6 minutes. Remove lid, lower heat to medium then add in garlic, lemon juice, and zest. Toss and cook for 3 more minutes until beans are bright green and done but still are crisp.

Step 2

Taste and season with salt and pepper. Serve immediately.
