Thanks to
@Schaefd2 I was inspired to go with fresh broccoli. And I decided to try tossing it straight over the heat with some Italian dressing dribbled on.
I went with mostly unlit coals in one charcoal basket. Not completely filled of course. I lit around 10 and dumped them on top and kept the vents cut down, about 1/4 at the bottom and nearly closed up top. I wanted them to go low and slow and to last since I wasn't using much fuel.
And also, because the machine in question leaks like a sieve.
Initial results were not promising. I'd done a seasoned buttermilk soak for chicken thighs and didn't know if I had put the fire out when they went on. It was only 4 thighs but too cramped with just one basket providing heat. I walked away and the skin burned. Not that any of us care about skin anyway, but they stuck to the grate. I moved them to the other side when (a little over) done.
Then, I did tenders with a simple seasoning. I didn't leave these alone and they turned out correct.
