Spaghetti Squash with Red Onion

Original recipe:

1/2 chopped red onion (I thought about also using chopped mushrooms or asparagus)
1 small spaghetti squash
4 diced garlic cloves
1 tsp cayenne pepper
1/2 tsp salt
1/2 tsp pepper
2 tbsp olive oil
1/3 cup shredded Parmesan cheese
Fresh or dried chopped basil

1.) Pierce spaghetti squash with a sharp knife several times before cooking.

2.) Bake squash, whole, in a baking dish at 375 degrees for 60 minutes.

3.) Once squash has cooked, set aside to cool.

4.) Heat olive oil in a large skillet. Once the oil is hot, saute onion and garlic.

5.) Slice squash in half (width-wise) and scoop out seeds and pulp.

6.) With a fork, scrape out squash into a bowl.

7.) Add to the skillet: squash, cayenne pepper, salt, pepper, and Parmesan cheese.

8.) Stir until mixed thoroughly. Top with basil.
