Have a look at Jamie Oliver's risotto recipes. He gives a basic recipe then lots of variations. If you haven't got the Naked Chef book or can't find the recipes on line (BBC recipe finder is v. good) then post again and I'll copy it out of the book.
Just make a plain risotto and add whatever veg you like - risotto should not contain cream anyway as the creaminess comes from the startch emitted by the rice.
Maybe use courgettes griddled and peas and chanteray carrots cut up into small pieces - any vegetable at all will work oh, and dried mushrooms are really nice expecially if you drizzle with truffle oil when dished up.
mushroom risotto is nice. Or you could try a risotto primavera. On that link is also a link to butternut squash risotto, another nice one. Cream is definitely a non-essential, I wouldn't dream of using it in a risotto.
For wheat-free pasta, I use the Orgran Rice & Vegetable or RIce & Millet (although the R&M is gtting harder to find now) - both fine.
Thank you ever so much. Will have a look at the recipes.
DS is what we say a carnivorous vegan (can't have most vegetable protein so we use meat instead) so when some one says vegetarian.... I start running in circles as I suspect some mothers do when I say how allergic DS is.
