You can also cook these twice-baked spinach potatoes in the microwave by piercing them with a fork and arranging them on paper towels. Microwave at HIGH 16 minutes or until done, turning and rearranging potatoes after 8 minutes. Let stand 5 minutes.
3 large baking potatoes (about 12 ounces each)
1/2 cup 1% low-fat milk
1/2 cup tub-style light cream cheese (about 4 ounces)
Pierce potatoes with a fork, and bake at 400° for 1 hour and 15 minutes or until tender. Cool. Cut each potato in half lengthwise; scoop out pulp, leaving a 1/4-inch-thick shell. Mash pulp with a potato masher. Combine milk and cream cheese in a large bowl, and stir with a whisk. Add potato pulp, 1 cup cheddar cheese, onion, salt, pepper, and spinach; stir well. Spoon potato mixture into shells; sprinkle each half with 2 tablespoons cheddar cheese. Place stuffed potatoes on a baking sheet; bake at 400° for 15 minutes or until thoroughly heated. Garnish with green onions, if desired.
