Yeah, they look pretty good, but if you have to go a bit long to say, get the bacon how you like, sometimes the other stuff ends out a bit over the top.....
Another possible strategy is like this:
the chicken & bacon stuff is over coals & the high risk shrimp is off to the side.......
Noticed the lighter meats like pork / chicken maybe need a marinade to keep them juiced, too.....
I'll slab zucchini thicker on a beef one (than say, chicken) so the slightly longer cook time matches up better too......
Great way to play with food.....kabobs, man.....
Have Fun !!!!
