Mmmm, sounds yummy!
I like all of the squash(s) that I can't get at the grocery store.
If you could find it, I'd also suggest Romanesco. This is the first year that I grew it and its texture and flavors are outstanding. Firm, smooth and just a bit citrus-y, perhaps.
I don't, however, think I'd try sage on that one.
I'll have a lovely mixed green salad with my next meal, yet tonight. I think I'll sprinkle sage on it as well. Do you think it would go well with hard-boiled egg?
