Also add as many of the following optional toppings as you would like:
chopped onion
sliced green onion
roasted red pepper
cooked garbanzos
fresh spinach leaves
thinly sliced tomatoes
marinated artichokes
basil leaves
Return to the oven and bake for an additional 5-10 minutes. (If you didn't put raw onion, it probably needs only 5 minutes. The longer time is only needed to cook the onion.)
