I ate a lot of canned Soups, pureed in the blender. Campbells makes a Cream of chicken Noodle that was really good, and Campbells Bean with Bacon pureed nicely and was still very tasty. I found that Chunky Soup, pureed in the blender, wasn't very good...kinda tasted like gritty brown gravy. Mostly the cream soups turned out the best.
Also one time I pureed some refried Beans and thinned them out with beef broth, melted some cheese on the top and some sour cream...it was really good. I know, not the best food choice, but at that point I was really craving something "substantial."
Another not so good choice, but something that tasted really good was Stove Top stuffing thinned out with chicken broth and pureed.
