Cut squash in half lengthwise and scoop out seeds and discard. Rub squash skin and inside with ½ tbsp. olive oil.

Place remaining broccoli florets, grape tomatoes, onion, and garlic in medium mixing bowl. Add 1 tbsp. olive oil and salt & pepper to taste. Toss vegetables.

Put spaghetti squash on grill flesh side up and other veggies.

The broccoli and veggie mix needs to cook about 10 minutes and the spaghetti squash an additional 15-20 minutes until you can pierce with fork.

Remove spaghetti squash from grill and allow to cool about 5-10 minutes. Then with a fork remove spaghetti strands from squash and place in mixing bowl with other veggies. Toss well.

Place spaghetti squash mixture back in shells and top with cheese and red chili pepper flakes.

Put under broiler or back on grill for just long enough for cheese to melt.
