Brown beef or turkey in a large skillet. Add Ragu sauce and turn heat to low.
Pre-heat over to 400 degrees.
Cut spaghetti squash in half and scoop out seeds (similar to what you would do with a pumpkin). Cover each half with Saran wrap.
Place spaghetti squash halves on a plate and microwave for approximately 9 minutes, until cooked.
Carefully remove Saran wrap and allow to cool for a minute or two.
Use a spoon to scrape out the spaghetti squash from the skin, careful not to puncture skin (if planning to serve with).
In separate bowl, add cottage to meat and sauce mix and stir well. Then, stir in spaghetti squash.
Fill each empty spaghetti squash shell with mixture until full.
Top with cheese.
Place full shells in a baking dish or 9x13 pan.
Bake until cheese is melted or browned, based upon preference.
Enjoy!
