I'm glad I tried this recipe, it wasn't bad, but it was really good either. I liked that it was different and it covered the taste of the cauliflower. Update. I've made this recipe a few times now and it's really grown on me. I did cup down the mayo/mustard to just 1/8 cup each and that made a big difference for me.
Tasty and not oversauced. I used Dijon mustard. I think you could play with all types of mustard in this recipe. I tossed my cauliflower in the mayo/mustard mixture (to evenly coat it) before pouring into the baking dish. Thanx for sharing; I'll make this again.
