Some prefer to slice acorn squash and roast them but I like cutting them in halves. To do this: - Cut the down the middle being careful as it can be hard to slice through. You may want to slice off the top with its stem if you run into trouble. - Slice off a small sliver on the round bottom of the half, so it sits stably side up. Scrape out the seeds and membranes using a spoon. You can either discard or clean and roast the seeds for snacking or garnishing of salads!
