Chinese Potato Salad

5−6 medium potatoes (about 2 1/2 pounds)
4 slices bacon, well−cooked and crumbled
3/4 cup chopped bok choy
1 red pepper, diced
1/2 cup chopped green onion
1/4 cup chopped cilantro
1 1/3 cup mayonnaise
1 tsp sugar
1 tbs soy sauce
1−2 tsp sesame oil
1/8−1/4 tsp hot mustard powder
1/8 tsp salt

Boil the potatoes until cooked but still firm. Cut into potato
salad−sized chunks. Mix the ingredients for the sauce together,
using more or less sesame oil and hot mustard according to taste
(the more the better, up to a point...). Put all solid ingredients
together in a large bowl, then add the sauce. Mix and serve.
