My favorite are Turkish skewers, they usually have ornate brass ends. They come in thin, for veggies or cubed meat and wide for meatball (like kofta) or even long thick sliced veg (like eggplant or squash). The metal heats it thru better vs wooden, super easy to clean and no waste like the wooden kind which also like to burn and snap off when you flip.
I've used the small cast iron dish. I love it, however it gets sticky and grimey and needs a lot of
water to clean (my partner bakes brownies in it...errr).
I'm about to try out tiles on the grill to make small pizzas, breads and certain veggies too, much easier to clean than the cast iron.
My old boat neighbor swore by the silicone sheets and it's on my
shopping list.
Btw, a favorite veggie side I like that's easy to make and one handed even for underway are fresh spring rolls. You need a plate for
water, quick soak of the rice disc and roll in the ingredients. Bbq veg is good, just wrap in lettuce, spine removed, with other herbs like mint and basil, so it's dry against the rice paper. 4 ingredient peanut sauce.
Its a great salad burrito thats low carb. I do a
Med one too, with tzaziki, or a tahini sauce one with some lentils in the roll for fiber/carb.....only have to grill the meat.
