I seasoned them with salt and pepper and put them on a baking sheet coated with cooking spray. They cooked for about an hour at 400 degrees, and then I turned the oven off and left them to roast some more in the cooling oven.
They taste, as husband said, not unlike a tomato craisin, if such a thing existed. Slightly caramelized, and quite tart, almost like a sundried tomato. They'll be lovely in an omelet, sandwich or with fish. Thanks, Mom!
