I've never had raw zucchini, always had it at least warmed up, usually cooked. I can say from experience that it's delicious in chili.

And with zucchini that big, you have another option: cut it in half, hollow it out, and mix the innards with stuff like cheese, and bake it. Delicious! But I haven't had it in ages because it doesn't work well with small zucchini.

Come to think of it, you could fill in the hollowed zucchini with spaghetti sauce and cheese, or some of that chili I gave you. (And then bake it.)
