Invited to dinner at friend's home. The man of the house likes to cook and he is creative and has as many misses as hits. This week he is thinking of adding wild rice to the arborio rice to make risotto. There will be 12 people. I know his risotto will be vegetarian and I want to bring a vegetable to make sure we are covered if the risotto doesn't quite make it. You now know what I know - any ideas?
