Hi, Jacquie,

Periodically I go vegetarian or mostly vegan.
Cheese, I hear on the Internet, is one of the most difficult things to give up -- depending on how much you loved it to start with.
I use Earth Balance Margarine in place of butter:

Here is a recipe for mac and cheese:

You can find simpler ones. The trick for the creaminess seems to be in the cashews. The nutritional yeast is important for taste as well.

Have fun on your family food adventure.
The butterfly garden will bring peace and beauty to your home.
