1) Chop the blanched green beans, cucumber, the cooked potatoes and the small tomato up into bite-size pieces. Add all this to a large mixing bowl.
2) Then stir the vegetable well. Chop up the bean sprouts as well and add them to the bowl too.
3) Stir the salad well again. Then divide the vegetable salad over deep plates. Peel the hard-boiled egg, slice it on half and add it to the salad. Top with the homemade peanut sauce. Sprinkle with the crushed peanuts. Serve at room temperature.
