This post is not so much a recipe as a suggestion. This is the time of year for creamy, wonderful mashed potatoes, made the allergy free way your family likes them.
Know what? You can freeze what you don't eat. Put them in a baggie, squeeze the air out, press them flat, pop them in your freezer. Instant side dish for any dinner in a hurry.
They also make a wonderful base for soup. Fresh or frozen, soup from leftover mashed potatoes is wonderful. I'd share my recipe, but I can't seem to find it. Drat! Add some grated carrots, some onion and celery, some broth of your choice....you can wing or just google it. There are tons of good recipes out there, and soup is pretty darn forgiving with substitutions.
Warm and hearty, mashed potato soup can be vegan, dairy free, soy free, gluten free, nut free, allergen free and very filling. Give it a whirl.
