I really don't know the difference between yams and sweet potatoes, so I was tweaked to find this!
It says it's a yam!
My Weight Watcher leader said you can roast yams until they caramelize themselves, but I chose not to wait that long.
I cut my yam into thin-ish slices.
I sprayed them with oil (from my silver WW oil sprayer ), sprinkled with salt & pepper (the Coke cans) and garlic powder, then I sprinkled brown sugar on them.
Since I was also making spaghetti that night, my oven was pre-hreated at 425 for the garlic bread, so I just put these in at the same time.
After 15 minutes, I flipped them over - salted, peppered, garlicked & sugared them - then baked for another 7 minutes or so.
Mr. Picky Randy had a couple after I encouraged him to try, and said he liked them. Little Miss Picky Angela had half of one, after I gave her "the Look" and said they weren't bad.
So I count this one as a success. I hope this works just as well with sweet potatoes!
