How to Make It
Remove the tops and bottoms of each squash. Cut crosswise into one-inch slices.
In a small bowl, whisk together the extra virgin olive oil, lemon zest, lemon juice, parsley, mint, garlic, salt, and pepper. Set aside.
Preheat the grill to medium-high (400°F to 450°F) or prepare a grill pan on the stove over medium-high heat.
Brush each side of the squash with the mixture—reserving and setting aside any leftover sauce—and grill for two minutes on each side. To achieve perfect grill marks, resist the urge to disturb the squash while grilling. Remove from the grill and serve immediately with the extra sauce spooned overtop.
