Rub the pork with coconut oil, then season with rosemary, salt, and pepper.
Heat the olive oil in a large skillet over medium-high heat.
Add the pork and cook for 2 to 3 minutes on each side until browned.
Sprinkle the cauliflower in the skillet around the pork.
Reduce the heat to low, then cover the skillet and cook for 8 to 10 minutes until the pork is cooked through.
Slice the pork and serve with the cauliflower.
