Wash and cut up your squash into bite size chunks and place in a bowl.
Toss with olive oil stirring to coat the squash. Add salt and pepper to taste.
Finally, place the squash on the grill and stir to prevent burning. While I have grill pans, I prefer lining the grill with aluminum foil. This allows me to cook a larger quantity at one time. Grill until tender - about 25 - 40 mins.
Notes
For variety: Add other spices such as garlic powder, lemon juice and even add other vegetables to the mix, such as, carrots, onions and/or peppers.
