Cut the potatoes into bite-sized pieces and soak them in water. Drain and place them in a microwave-safe bowl. Cover loosely with plastic wrap and microwave at 600W for 4 minutes.

Cut the bacon strips in half lengthwise.

Mash the microwaved potatoes while hot. Add salt, pepper, and milk, and mix until smooth to create mashed potatoes.

Weave the bacon strips into a lattice pattern, matching the size of your rectangular frying pan.

Line the frying pan with plastic wrap. Add half of the mashed potatoes and flatten. Place cheddar cheese slices on top, then add the remaining mashed potatoes and smooth out. Place the woven bacon on top.

Wrap the mashed potatoes with the woven bacon. Cover the frying pan with a lid and flip it over.
