Given the recipe, one serving equated to about 40 green beans from this brand of French green beans at Costco. That's about 6 oz. Of course, if you're not measuring, just cook a bunch and adjust your seasonings accordingly.

I also didn't have a lemon, but I did have lemon juice, so I left out the grated lemon peel. What a handy dandy bottle. It's all about quick turn around some times, especially when you're hungry.
6 oz green beans, ends trimmed
1 Cup water
1/2 tsp extra-virgin olive oil
1 tsp Fresh lemon juice
1/4 tsp finely grated lemon peel
sea salt (to taste, optional)
1. Place green beans and water in medium saucepan over high heat. Bring to a boil. Reduce heat to maintain a gentle boil; cook, covered, for 3-4 minutes, or until tender-crisp. Remove from heat. Drain.
2. Combine green beans, oil, lemon juice, and lemon peel in small bowl; mix well. Sprinkle with salt (if desired).
