This is a really tasty dish which we like as part of a Japanese meal- usually we'll serve with a tofu miso soup, steamed short grain rice and a salad made with Japanese-Style Miso Salad Dressing. I'm not sure how many serves but would serve 4 in this style meal. To make it faster, I often microwave the potato for 5 minutes first and leave out the water when baking. This way it's done in about 30 minutes.

This was so quick and easy to make and tasted so yummy - and complimented the chicken and crunchy stir fried veges that were served with it. I used purple kumara and toka toka (the orange kumara) which is what we call sweet potato in New Zealand. The flavours weren't overwhelming and it didn't taste salty - I used Japanese organic tamari, which is wheat free. The sesame seeds at the end were a nice touch, I think this would taste great with or without the shredded nori so leaving that out if you don't have it wouldn't make a significant difference. (I also didn't cover it and it didn't seem to make a difference to me, but I had everything crammed in a small dish so maybe this why). Thanks for posting this Chickee, I'll definitely make it again.

That would definitely change things. If you roast these uncovered in a single layer, the liquid will harden and solidify to the pan, and not be as flavorful. I'd recommend putting them in a casserole with a lid.

These tasted quite good. I have some thoughts on modifications I'll post when I have experimented!
