When my husband and I were dating I made him a box of "bachelor chow". It was meant as a joke, but he ate it!
To the OP, I think it is wonderful that you want to cook healthy foods for your wife.
I made a Grand Marnier Souffle with Creme Anglaise for dessert last night. First time I've made it since going gluten free. I just substituted cornstarch for flour and it came out fine.
