Bunnies can eat more than one type of hay. If alfalfa bothers you, you could try timothy. Although it might be hard to always buy the type that doesn't bother you. i think the local house rabbit society sells a mix (at least they used to - it has been years since I had a bunny).
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.
