This is in the category of "things you should not assume your kids won't like". A friend of mine (thank you Kristen!) served it at dinner a few years ago and I was amazed that my then 5 year old daughter loved it. I really was shocked! However, my then 7 year old ate it but I'm not sure he loved it. I'm okay with that.
Preheat oven to 375F. If you have convection, use it for this dish.
I use about 1/2 of a cabbage for our family of 4. Many grocery stores will cut a cabbage in half for you if you don't think you will use the rest.
Remove the white core from the middle. Cut the cabbage into wedges.
Drizzle with olive oil. Season with salt and pepper.
Roast about 12-15 minutes or until you can smell the cabbage. Cabbage should be tender with a little browning. Serve as is.
