Weedwhacker said: That certainly looks delicious - and most vegetables seem to benefit from roasting, I need to give it a try with the squash!
They fare very well in a mixed veg roast, with small whole onions, mushrooms, zucchini, broccoli and/or Brussels sprouts, and any colour of pepper. Some people put in whole tomatoes, but I find roasted tomato skin too tough.
With the scalloped squash, I didn't wait: I picked them very young and pickled them. Sometimes with baby melons and zucchini for a pleasing condiment display.
