In a large skillet cook green beans in hot oil over medium heat for 18 to 20 minutes until crisp-tender and lightlybrowned, using a spatula to gently lift beans occasionally to prevent them from sticking. Meanwhile, shred 1 teaspoon of lime peel. Cut lime in half. Add lime peel to beans. Cook and stir for 1 minute more.
Lightly season beans with salt, drizzle with lime juice, and serve immediately. Makes 4 (1/2-cup) servings.
