I like the bechamel deal, I'd add some cheddar and make the sauce a little cheesy. Nodody has mentioned any BACON, gotta have some bacon on there. I think about mom's cheesy cauliflower with bacon and those French's onions on top, that might be something too, those crunchy onions. Yes, blanch and roast or toast up in one of those grill woks. I'm thinking more of a comfort thing like mac and cheese deal. Something to ponder, may have to try this one on too!
