We're gonna have to try that. I've mashed turnips, butternut squash, and sweet potatoes as a substitute, but hadn't thought of cauliflower.
A good snack food swap if you want something crunchy like potato chips or popcorn, is baked kale. Take some kale, rip it up into pieces, spread a single layer on a baking sheet, dribble a little olive oil and sprinkle some sea salt on top, bake at 350 for 10-15 minutes when edges start to brown. I didn't think it would be that good, but the kale turns into the lightest crunchiest thing and you can't stop eating it.
