Getting colder here up in the northeast, but we're getting some of those final bumper crops of certain veggies at crop share, summer squash and zucchini still. I love grilling them up for sandwiches and wraps during the week along with some eggplant and cheese, or pan bagnat style refrigerator sandwich. The zucc and squash are a little annoying to grill, when you cut them into slices they fall apart, or there's like 40 pieces on the grill that become tough to manage. This isn't anything earth shattering, but a little idea i toyed with tonight that worked pretty well.
Cut them in half down the length. Scrape the seeds. Cut the top solid part into three fingers. Rub with oil, make sure to get it in between the fingers. Salt, do whatever season you like. Grill face down first, flip over, do the other side. After that, I flipped it over to the inside again, and i smashed the seed part down to get flat against the grill.
Worked pretty well. Kept it together, they didn't fall apart, and they are thick enough to use in all the other applications that they wouldn't be too thin or mushed.
