Compliments of "Moosewood Restaurant Cooks at Home," this is by far my favorite soup recipe ever. I love how the broccoli did not overcook to that darker, nearly brown color--even after sitting a while. I used purple onions and orange bell peppers to create a true variety of color pleasing to the eye and to the taste buds. The color of the broth comes out a rather bright yellow when the egg and lemon are added. I feel you could easily skimp a bit on the egg and do just as well. I chose to use brown rice and was very pleased with the results, but it's nice to have a variety of options for cooking.
For vegan friends, I would like to try using cornstarch as the thickening agent as the egg is very useful in keeping the soup on the thicker side. But it's just too good to not share with everyone!
