See I don't know, because I have no fucking idea what pumpkin chili is supposed to be. You're talking to a lady who's made chili with pineapple in it before. I'm extremely liberal in my chili attitudes.
-I only used 1lb of ground meat (I used turkey) -I most definitely used less than a whole onion -I used a can of kidney beans and a can of cannellini beans -I used an entire can of canned pumpkin. -I skipped the tomato juice and instead went with one large (28oz) can of diced tomatoes and 2 medium sized cans (don't ask me for more details on the size ... it's medium) of tomatoes with jalapenos. -I make my own pumpkin pie spice, but am positive that if you combine the cinnamon, nutmeg allspice etc that I used it was definitely over 1 tbsp -I also added paprika and maybe a dash of cayenne
Ok, so pretty much the only thing I did as instructed was use a whole green bell pepper, but it's delicious. Most of the things I changed are minor, but you will want to add some additional spices at the end
I made a recipe for Chipotle Pumpkin Black Bean Soup once. It's a Rachel Ray recipe from The Big Orange Book. Topped off with Apple Pico de Gallo, and sour cream. I always thought it would have been delicious with some chicken in it, but it was really delicious and filling as it was.
But I've never made pumpkin chili. It sounds good though.
