Heat two teaspoons olive oil in large skillet. Add green beans and cook for 8 minutes on medium-high heat, stirring frequently. Beans will start to char slightly.
Add 2 Tbsp. lemon juice and 1 Tbsp. water to the beans, cover, and turn heat to low. Cook 2 more minutes. Remove lid and continue to simmer until water has evaporated.
Add salt, pepper, and another drizzle of fresh lemon juice. Serve immediately.
