Substitute for mac and cheese?

Currently in my 3rd week of keto, already lost 2kg and body fat down by like 2%, but I'm really having a craving for something like mac and cheese (I guess I'm not adjusted yet). I had a keto pizza a few days ago which was amazing, and pancakes that were okaaaay, but mac and cheese would make my day. Have you found any good recipes/ products that could satisfy this craving?
