I had to google it too--looks like it's a winter squash like acorn squash rather than a summer squash like courgette. When I was growing up my mom always baked acorn squash with butter and brown sugar in the cavity. Maple syrup would be good too, I bet.
Some of the other things that I really like with winter squash are goat cheese, leeks, walnuts, cranberries, sage, thyme...lots of autumn flavors.
I love getting random things in my veg box, too. I'd be happy to see some of those guys! Enjoy!
