Slice zucchini lengthwise into 3/4" planks. I just make three planks out of a medium-size zucchini. (One zucchini is about the right serving size per person.)
Drizzle lightly with canola oil, and sprinkle with salt and pepper. You could add a little garlic powder if you are a garlic fan. Toss to coat.
Enjoy your healthy grilled veggies with your summertime feast!
