I switched to squash a few years back in my first round of cutting carbs. I really love yams but squash is better for me.
Any particular type of squash, and do you want to go savory or sweet? Some of the casserole and spiced recipes get pretty sweet. You can now get cubed butternut (or similar) squash in the freezer section which makes it easy to deal with.
edit: I usually go to cooks.com for general instructions like "how l long is this likely to take and what temperature to cook at", you can search by general ingredients.
Here's a more savory casserole that can be done ahead:

here's one more like the yam and marshmallow sweetness level

here's a still sweet but lighter option, I've done squash and apples in several ways, can look nice with the fancy shaped ones and I've left the skin on for style -- always easier for eating if it is removed!
