I don't cook in the microwave except for these.......
White Potatoes sliced thin in rounds......quantities similar to fried for your household
1 stick butter
Water....appx 1/2 inch in dish
Season to taste
Place all in covered Pyrex Dish, nuke on high x 6 min, stir, cook appx 6 more or till done.
That is your base recipe and they are absolutely wonderful plain. You can leave skin on or peel, add milk at the mid stir for creamy, add onion, cheese, diced ham, kielbasa in any combination.
