I can thank a counter of dirty dishes for this discovery. For lack of other options, I grabbed a loaf pan just to have something to hold the asparagus as they waited their turn on the grill. I quickly realized what a perfect vessel a loaf pan is, not only for asparagus, but for kebabs, halves of zucchini, chinese eggplant, fava beans, and other long skinny foods.
The high sides keep the foods contained, and because the food is at an angle, it easier to grab with tongs. Several loaf pans next to the grill are also more organized and take up much less space an bowls.
I use casserole dishes to carry food to the grill as well, but when they're dirty (ahem...) or if I need more space, loaf pans it will be.
