To the pot add the green beans and 2 1/2 cups of water or chicken broth to the pot. Season with 2 tsp of garlic salt and 1/4 tsp black pepper. Stir well.
Cover, lower the heat and simmer for 30 minutes.
After 30 minutes, uncover and arrange the halved potatoes over the green beans. Sprinkle the tops with 1/2 tsp garlic salt and a few turns of black pepper. Dot with cubed butter.
Cover and continue to cook over medium-low heat for another 50-60 minutes until the potatoes and green beans are fork tender.
Crumble the cooked bacon and sprinkle on top just before serving.
Notes
If you prefer, you can omit the bacon drippings and use 3-4 Tbsp of olive oil instead.
