While the chicken is marinating/cooking, make the grilled zucchini. Slice the zucchini into 6-8 thick slices. Brush the slices with the olive oil, and sprinkle the salt, pepper and rosemary. Place the zucchini slices either on a grill, grill pan
or over a roasting rack
for the oven/toaster oven. If using a grill or grill pan
, place over the grill and cook until tender, about 5 minutes, and flip halfway through. If using an oven, place the zucchinis on a roasting rack
and cook about 20-30 minutes at 200C/400F or until tender, flipping them halfway through.
