An easy way to prepare zucchini is to slice it lengthwise into long strips and to grill them on a prepared and preheated grill pan. To prepare the grill pan spray it with some cooking spray and after it is preheated lay the zucchini on the grill pan. Season with ground sea salt and freshly ground pepper. Cook the zucchini turning it every few minutes until done. This is really quick – 10 minutes maximum. Place in a bowl and sprinkle quality balsamic vinegar over them. Season with more salt and pepper if desired.
