Oh wow! This is delicious. The carmelized onions and cocoa give this a very unique taste. I love the balsamic with it as well. I left out the butter and oil, and my onions carmelized just fine in water. This will make for some great lunches this week. We'll eat it with pita bread and baked veggies. Thanks for posting!
Healthy and easy, but rather bland tasting. I like the concept, but I would try it again with a lot more of the garlic/vinegar/cocoa/pepper. As written, it's mostly bean paste, with a one-note of onion.
