In a food processor, blend the broccoli stems with the lemon juice, cumin, and garlic powder until completely smooth. Add the remaining ingredients and mix well by hand, but do not blend. Chill before serving for best flavor. Note:the above was copied directly from the book. I doubled the recipe. I also used a fresh green chili instead of canned, which I don't think I can get over here. It was very tasty, but do not expect it to taste like avocado. Think of it as a really good broccoli dip, and not necessarily as a replacement for something else. Everyone at my party the other night enjoyed it.
