I have recently Found that the secret is to cut them in half and steam them first in the microwave or however you want. Then toss them in olive oil and salt and roast. I also add a penzeys spice mix like mural of flavor. I do 400° and Turn them over when they are browned. For years I was just roasting them directly and, by the time they cooked enough to be eaten, they tended to get burnt.
