Clean the squash and pat it dry with paper towels.
Cut each of the squash into quarters, lengthwise.
Coat the squash spears with the olive oil and season them with garlic powder, salt and pepper.
Preheat the grill over medium high heat (approximately 350 degrees Fahrenheit) and rub oil on the grill grates to prevent the squash from sticking to the grill grates.
Cook each side for approximately 3-4 minutes per side until the squash is just fork tender. Watch them closely to make sure that they do not get over cooked.
Remove from the grill, serve immediately while warm and enjoy!
Notes
Refrigerate the leftovers in an airtight container for up to 5 days.
