Chili PP here, I also found a recipe last week for a winter vegetable hash. I sautéed potatoes, peppers, diced squash and onion. Added olive oil, some herbs, etc. Covered and let it steam to cook through. About 5 min before it was done, I added in some chopped Swiss chard, kale works too. It was amazing. I have several small squash in the fridge as my CSA is coming to an end and they aren't really big enough to bake as its just a few bites, but this was perfect and adding the potatoes gave me the quantity I needed.
Sorry for the hijack, I just love squash.
