I'll share the foods that are on my list of pureed and very soft foods, but some that spring to mind are:
Nonfat yogurt (regular and Greek)
Nonfat cream cheese (weird to think of just eating some cream cheese, but OK)
I've also been eating unsweetened apple sauce and enjoying it, may try sprinkling some cinnamon on top.
