Wash and trim the green beans, and scrub and cube the potatoes into 1-inch pieces.
In a large skillet or pot, combine the cubed potatoes and chicken broth.
Cover and simmer over medium-high heat for 12 minutes until potatoes are partially tender.
Add the green beans to the pot with the potatoes.
Cover and continue cooking for 10 minutes, or until both vegetables are fork-tender and liquid has mostly evaporated.
Drizzle the melted butter over the vegetables and sprinkle with the dry ranch seasoning mix and black pepper.
Toss gently to coat all ingredients evenly.
Garnish with crumbled bacon before serving.
