It's always nice to find new amaranth recipes, and this is very good. I'd only ever used amaranth in wheat-free bread or hot cereal recipes before, but here it compliments the soup with a hearty, almost nutty taste very, very nicely. We like chunky soups, so I didn't puree it. Probably because of that, this wasn't very soupy, so we had it over basmati rice.
I was looking for some way to cook Amaranth. My entire family liked this - toddler and husband included. I only pureed some of the beans before putting them in, not the rest of the soup because my food processor is not heat-proof. And I used a can of fire-roasted tomatoes instead of the puree. I liked the chunkier texture.
Love this soup, didn't have the amaranth so I just skipped it. Easy to make and delicious.
