This is still a work in process. I don’t quite have all the amounts down right. Last time I made it I used too much oil and salt; hence those don’t have measurements below.

  Amount  Measure       Ingredient — Preparation Method
--------  ------------  --------------------------------
       3  cups          potatoes — rough cubed
       3  tbsp          mayo
     1/2  tbsp          mustard
     1/2  tsp           ground black pepper

Toss the potato cubes with oil and salt. Spread out onto a pan, making a single layer. Bake 350℉ for about 45 minutes. Stirring them up once or twice. When finished, transfer to a bowl and toss with mayo, mustard, and pepper. Serve warm.
