I've been making a lot of pumpkin muffins lately. They aren't low-fat or low-sugar, but they are only 150 calories a piece and I make them whole wheat. I can work 150 calories into my breakfasts easily.
I haven't done it this year yet, but making no-crust pumpkin pie is always good. I just bake the filling is greased ramekins for individual sized portions. The crust is what makes pie a calorie bomb and I like it for the filling, so I don't miss the crust.
I also make all our bread, that we eat. Lately I've been making this pumpkin yeast bread:
