Heat grill (or grill pan on stovetop) to medium-high heat.
Spread the squash slices out over a cutting board.
In a small bowl, combine the olive oil, salt, pepper, and garlic powder.
Brush or pour the olive oil mixture over both sides of the squash slices.
Place the squash on the grill and allow to cook for 3 to 4 minutes, till grill lines have formed, flip squash and cook for an additional 2 to 4 minutes till tender.
Place yellow squash strips on a large platter. Sprinkle on the parsley and serve immediately.
Notes
Storage - While the sautéed squash is best served fresh, you can save leftovers in the refrigerator for up to 3 days in an airtight container.Reheat - in the microwave in 1 minute increments. The squash will become a little soggy when you reheat it, so consider adding it to something like risotto or pasta that would benefit from the moisture.Cooking Tips - Yellow squash cooks quickly and can become a soggy mess when overcooked. Make sure to watch your squash closely while it's cooking. An additional minute or two of cooking can take squash from perfectly tender to overdone. If your squash starts releasing a lot of water, remove it from the heat.Recommended Tools - I like using a large nonstick skillet for this recipe.
