New Year's Pumpkin Soup

This recipe came together rather by accident - a mix of homesickness for fall in North America, a pumpkin sighting at my local grocery store, the Haitian tradition in my family of having some sort of pumpkin soup (soup joumou) on New Year's, and the delightful discovery of smoked tofu for sale at a 'meat' shop (protein shop?) near work. You may not have smoked tofu available where you live, and if that's the case I am profoundly sorry. It seriously rocks my world! Depending on what I've had in the house I've substituted potato for the tofu and it makes an equally lovely soup, so use what you've got available!
