Prosciutto: no - bacon won’t work, it won’t cook fast enough! You could skewer some salami around the figs!
Figs: peaches, apples, pears…
Cheese: literally any kind of cheese would be delicious. I don’t think you can go wrong!
Honey: balsamic glaze would also be tasty!
Thyme: finely minced rosemary. You can also use a tiny pinch of dried herbs, just be sure to smash them between your fingers as you sprinkle them on top so that you don’t get a hard bite.
