In large skillet over medium-high heat, bring the broth to a simmer. Add the green beans, cover pan, and cook, tossing occasionally, until crisp-tender, 5 to 7 minutes. Uncover pan and add butter; toss to coat.

Step 2

Remove pan from heat and stir in the za'atar, lemon zest, salt and pepper to taste before serving.
