Another recent success was dairy-free cheese sauce. It is nut-based and had a remarkable creamy, cheesy flavor. We used it one night on smashed potato nachos and later in the week in a potato lasagna.
Just a few of the more unique options of late that keep us away from sugar, dairy, and gluten. We still take breaks and indulge in food that contain these, but now prefer the convenience and yummy (addictive) sweetness only occasionally.
