Pork Tenderloin with Baked Sweet Potatoes
Preheat the oven to 140°C (approximately 275°F). Line 2 baking sheets with parchment paper.
Scrub the sweet potatoes thoroughly, halve and thinly slice. Place on a baking sheet, sprinkle with 2 tablespoons of oil, season with salt and bake on the middle rack of the oven, turning the potatoes over midway until golden brown and crisp, about 45 minutes.
Season the pork tenderloin with salt and pepper. Heat 2 tablespoons of oil in a skillet and saute the pork until golden brown on all sides, remove and let cool briefly. Place the pork on a baking sheet. Mix together the mustard and the cumin and brush all over the pork. Roast the pork 30 minutes.
Heat the butter in a skillet, add the beans and a splash of water, cover and cook until the beans are tender, about 10 minutes. Season with salt and pepper and serve with the potatoes and sliced pork.
