Scrub potatoes. Make shallow slits around the middle as if you were cutting the potatoes in half lengthwise. Bake at 350°F for 30 - 60 minutes until done, depending on size.

Peel broccoli stems. Steam whole stalks just until tender and chop finely.

Carefully slice the potatoes in half and scoop the insides into a bowl with the broccoli. Add milk, 3/4 cup cheese and pepper. Mash together until the mixture is pale green with dark green flecks. Heap into the potato jackets and sprinkle with remaining cheese.

 Return to oven to heat through (about 15 minutes).
