1. Puncture the potato skin with a fork 3 times to prevent it from bursting.

2. Place a bacon rack on the turn table. Arrange the potatoes on the bacon rack, opposite each other leaving the center empty. (There is no need for a cover. The potato skin is a natural wrap.)

3. Cook on HIGH (1200W) for 7 – 8 minutes or until a fork penetrates easily.

4. Cut a cross on top and pinch both ends toward each other to open the potato. Sprinkle with salt and place the cheese on the opening. Cook another minute or until the cheese melts.
