jen, I don't think that pumpkin is techincally phase 1 friendly being that it is a starchy, winter squash.
that being said, you could probably put it in a smoothie for a less detrimental off plan treat. I made a good one the other day with pumpkin puree (maybe 1/4 cup), pumpkin pie spice, a good heaping spoonful of cottage cheese or ricotta and some milk (or almond milk) to get it going. you might want to add some splenda or vanilla to taste.
For that roughly first chop the onions and pumpkin. Add to a large saucepan, the Onions, Pumpkin, Water and Chicken Stock Powder. Simmer until Pumpkin and Onion are very soft. The Pumpkin will begin to fall apart.Take the soup off the heat. Allow to cool for 10-15 minutes. sing a barmix, puree soup until it is all a smooth consistency.
This idea of stirring pumpkin pie spice into SF yogurt just might get me past my pumpkin cravings... There is something about pumpkin anything this time of year! :-) I have need to get some more SF pumpkin coffee syrup! :-)
