Simple and delicious! I scaled back the butter mixture per serving, but the flavours still permeated the potatoes. I served with Miso-Glazed Cod (a Weight Watchers recipe) and stir-fried onions and zucchini.

I scaled the recipe down and used white miso. I loved the flavor it gave! I served with Szechuan black eyed pea salad and sticky rice. What a great meal I had! Thanks! Made for the Countries of Asia Challenge-Zaar World Tour#6 by a Looney Spoon Phoodie!
