A different kind of potato salad--this one boasts Okinawan Sweet Potatoes (purple flesh), a medley of red, yellow, orange and green bell peppers, and red onions. It's tossed in a tangy honey-mustard dressing right before serving. Delicious and nutritious! If you count the time it takes to chill down the potatoes, this salad takes about 1hour and 45 minutes to prepare. Or, steam the potatoes a day ahead, and it will only take about 1/2 hour!
