I made this up, but someone else probably did too and I haven’t had time to see if that is true. Anyway, this is simple:
4-5 yams, peeled and cut into 1/2 inch disks
1 red onion, large dice
Coat in olive oil, pepper and salt to taste.
Roast in a 350 degree oven for about 45 minutes or until potatoes are fork tender.
Toss with a few dashes of ground thyme and ground curry.
