In a microwave safe bowl, add the spaghetti squash.
Pour in a splash of milk (about a tablespoon).
Sprinkle cheese on top.
Sprinkle salt, pepper and onion powder.
Stir in baby spinach.
Microwave covered and on high for 30 seconds. Stir. Microwave for another 30 seconds if cheese needs to melt more. Mac and Cheese is ready once cheese is melted and the squash is hot.
Top with more Parmesan cheese if you like.
