Risotto can definitely work without cream, I have never put cream in, and I don't tend to use creme fraiche either. As long as you don't over cook it so it's still very moist, it will be yummy. Then drizzle olive oil and lots of Parmesan!
Can you use sour cream? Or milk? I rarely use cream.
If you can cope with milk then you can fry the chicken and mushroom in butter, sprinkle with a bit of flour, soak up butter a bit then slowly add milk, stir till thickened. (basically a classic white sauce but all in the same pan).
I bung in some ham and frozen peas then cover with puff pastry to make a delicious pie.
Just an aside, when I had gallstones cream didn't agree with me either and I used alpro cream. Infact I still sometimes use it in fish pie and a few other things and no one can tell the difference. But then I'm not big on that farm yardy taste that full fat dairy products have and don't tend to eat them much anyway. But you could give it a try, has about the same fat content as Elmlea I think (which I also sometimes use - check out Jamie olivers 30 min chicken pie, I do this with mushrooms and elmlea, as well as the leek).
