I've made this so many times, and my friend Debra loves it, too. Because it happens pretty fast and with very little effort. I made it after work today and I'm not feeling that great.
Here is Anna's recipe, but all you need to do is chop an onion and three garlic cloves and saute in olive oil for a few. Add two quarts of chicken broth, two potatoes diced up and two heads of broccoli, cut up. Cook, covered for forty minutes. Blend most of it. Adjust seasonings if you like.
