I bought a spiralizer, which is a really fun kitchen tool anyway, and now I make spaghetti-like strands with peeled zucchini. I put them in a pan, cook the water out of them, then saute them in butter. Top with a little more butter, cover in Parmesan, and it's awesomeness on a plate.
You can also cut an acorn squash in half from stem to bottom, bake in a 350F oven for about 30 minutes or so, then fill the center hole with butter and cinnamon and serve. Really good.
