Heat the oven to 425°F. Halve the potatoes, cut the carrots into 2-inch pieces and the onion into wedges.
Toss the vegetables with 2 tbsp oil, salt, pepper and half the rosemary, spread on a sheet pan, and roast 10 minutes.
Rub the tenderloin with the remaining oil, garlic powder, rosemary, salt and pepper. Stir the Dijon and honey together.
Push the vegetables to the sides, set the pork in the middle, and brush it with the honey mustard.
Roast 18-22 minutes, until the pork reads 145°F inside and the vegetables are tender. Rest 5 minutes before slicing.
