Carrots are hard for me to digest sometimes.
Do you do anything interesting with Rice milk or other "special" milk? I know you said soy doesn't work well. How about pastas that are pretty much broken down, like cous cous. Yeah, they're starches but. . . I made a ratatouille on cous cous I really liked and that seemed to go down well; it had a lot of mushrooms in it as well as eggplant and zucchini and chopped tomatoes but only a tablespoon of tomato paste; that surprised me for some reason.
Did you see this?
