Slice approximately 6 to 8 potatoes into 1/2 inch slices. Place them on the bottom of a microwave safe dish. Take 2 sticks of butter and slice into pats. Distribute the pats of butter evenly over the top of the sliced potatoes.

Slice one large onion into rings and then place the rings over top of the potatoes and butter. Season with salt and pepper. Cover with plastic wrap and place in the microwave for 20 minutes on high. THAT'S IT! THEY'RE GREAT!
