Oh my gosh - Green Been Casserole!!! And it's made with coconut milk so it's dairy free.
Mashed Cauliflower Green Bean Casserole - Contentedness Cooking
Of course, those who can have dairy would probably want to use cream.
For the topping I would probably use crumbled LC bread, or possibly broken up pork rinds.
I'm also thinking I could use a bag of frozen cauliflower.
Going to make this real soon - maybe this weekend.
