Might be too late, but Craig came up with a side dish that uses zucchini and/or yellow squash. Use the food processor to finely grind up some Ritz crackers. Slice squash and onions thinly. Butter a casserole dish, make a layer of squash, then onions, S and P, sprinkle moderately with Ritz crumbs (just a nice sprinkle, not heavy as it gets a mealy texture if you use too much), dot with butter, repeat until full. Bake at 375 for 30-45 minutes until knife goes all the way to the bottom easily. Remove from oven, allow to cool a bit and serve.
You can always make fried zucchini slices too with a tempura-like batter or a beer batter. A long closed restaurant served them with a dip of soft whipped cream with S and P and horseradish folded in. Yummy!
