Can I substitute something else (less fattening) for cream in a recipe?

I want to make a tortellini with avocado cream but without the cream. Will 2% milk work as a substitute without affecting the flavor?Can I substitute something else (less fattening) for cream in a recipe?
The milk will leave it weak and watery. I always use Fat Free Half and Half. It works beautifully and is creamy, thick and delicious.Can I substitute something else (less fattening) for cream in a recipe?
yes definatley, creme fraiche half fat, not sure if you can get it in the states though but thats what i use here in the uk. good luck.
Try evaporated skim milk.
they sell a non fat milk that tastes like 2 % hood and a fewother suppliers make it
Creme Fraise is your best option
