Diane invented this recipe when her son was dealing with so many food allergies she despaired of him eating anything. It's quick to make, healthy and stores well.
Combine ingredients by blending or whisking. Refrigerate the mixture until cold and thickened. It will become almost solidified. Stir before using, this promotes a uniform texture/flavor.
You can also flavor the spread(i.e. garlic powder, a pinch of salt, herbs, etc.) This makes a really good garlic bread spread.
BL's notes: if you want or need to make more at one time, do it in the food processor or with an immersion blender (hand blender). If you are on a yeast free diet you can skip the nutritional yeast flakes too, but you will have to add a little salt and/or herbs to make it taste closer to "margarine". It is not the additives that make it a spread but the blending which incorporates air. Adding the calcium will make it opaque like store bought margarines.
