Even if it has to be silently. I know you want to share all the new and exciting things you are finding and trying with hubby, but until he's ready...not much you can do.
A tip, I do have a kitchen cabinet for all "my" stuff. It mainly helps me stay out of the bad stuff that everyone else still chooses to eat. I also keep fruit and veggies around just in case someone else gets the urge to eat right.
It doesn't help to argue about food and the family. Slowly integrate new recipes in and they'll never know the difference. Especially the little one.
