Start by placing the chicken in the middle of the slow cooker.
Next, add the green beans on one side.
Then for the potatoes, you will need to mound them high off to the other side.
In a medium-sized bowl, whisk together the lemon juice, olive oil, oregano, salt, pepper, onion powder, and garlic cloves.
Pour this mixture evenly over the chicken, green beans and potatoes.
Cover and cook on HIGH for 4 hours or LOW for 7 hours, without opening the lid during the cooking time.
