Make the dressing: In a small bowl, whisk together all of the
ingredients and put aside.
In a medium bowl, combine the olive oil, garlic, chile pepper and
comino seeds and mix well.
Add the squash and zucchini planks and
toss well so the squashes are completely covered with the mixture.
Place the squashes on the grill over a medium-hot fire and cook for
about 3 minutes on each side, or until well browned.
Remove the
squashes from the grill, place on a platter, drizzle with the
dressing, and serve.
