Wash the potatoes thoroughly with the skin on. Place chopsticks on both sides of each potato and cut slits 2–3mm apart without cutting all the way through. Soak in water and drain.

Cut the bacon into 5mm wide strips.

Arrange the potatoes on a microwave-safe dish, cover loosely with plastic wrap, and microwave at 600W for 5 minutes.

Drizzle olive oil and sprinkle salt and pepper over the potatoes. Insert bacon and shredded pizza cheese alternately into the slits. Sprinkle grated Parmesan cheese on top.
