In a skillet over medium heat, heat the avocado oil. Add the fresh green beans. Toss to evenly coat the green beans in oil. (Or use tongs to stir)
Squeeze half the lemon over the green beans and add salt and pepper to taste. Toss again.
Cook for 8-10 minutes or until green beans are bright green and beginning to soften.
Remove from heat and place on a serving platter with the other half of the lemon cut into slices.
Place leftovers in the fridge in a covered container for up to 4 days.
