Slice potatoes and add to a large pot and fill with cold water. Salt the water and bring to a boil, simmering until the potatoes are just fork tender. Drain & rinse with cold water to stop the cooking process.
Heat a large cast-iron over medium heat while the potatoes dry on a towel. Add a few tablespoons of cooking oil to the skillet and continue to heat for another 30 seconds.
Add the potatoes and to the skillet, frying on each side until golden brown. Work in batches if needed and place browned potatoes on a plate.
When potatoes are done cooking, add another tablespoon of cooking oil to the skillet if needed and then add the sausage.
Sauté the sausage for a few minutes until slightly browned. Add the sliced green beans and onion to the skillet. Season with thyme, garlic powder, salt and pepper and continue to sauté until veggies are tender and sausage is browned.
In handfuls, wilt in the kale. When wilted, add the potatoes back to the skillet until warmed & ready to serve.
