Do you like eggplant? It's lowcarb/nonstarchy & delicious. The japanese ones are the best. Fabulous paired with zucchini , a menage a trois with mushrooms. Pretty darn simply good (peeled & blended it is so naturally rich/creamy! Like eating babaganush virtually!). Even unpureed I find it quite safe.
(Just thought of that one as I stuck a little one in the oven!)
