I don't use much mayo - never did. I usually buy the smallest jar to make sure it doesn't go bad.
Just checked my fridge and I have Best Foods Vegan Dressing and Spread. Hellman's is called Best Foods west of the rockies (it says that right on the label - but I swear I didn't know that 2 minutes ago. )
Ingredients:
canola oil, water, modified food starch (potato, corn), distilled vinegar, less than 2% of: sugar, salt, lemon juice concentrate, sorbic acid, calcium disodium edta (used to protect quality), natural flavors, paprika extract (for color).
