Spaghetti Squash-Spinach side (A healthy chip dip?)

Since my husband was such a surprising fan of spaghetti squash, I bought some more last week. I was planning to look up another fabulous recipe online, but both of our computers were down. So I had to improvise. I finally decided to just add to my basic creamed spinach and see how it turned out. The girls thought it was fun the first time I served it to them, but didn't really want it the next day. But my husband surprised me. He loved it and said it was kind of like a spinach chip dip. The next thing I knew, he was getting his tortilla chips out of the pantry and dipping them in my spaghetti squash! The man never ceases to amaze me :) I didn't really see the connection with the chips, but I did enjoy my side dish. So here it is:

Ingredients:
1 spaghetti squash
1 box frozen spinach, thawed, or fresh baby spinach leaves
1 stick of butter
one small sweet onion, diced
5 cloves of garlic, chopped finely
4 Tbs. flour
1 cup milk
cheese as desired (I use any combination of swiss, cream cheese, parmesan, etc.)

Directions: In a large stock pot, put about 2-3 inches of water. Cover and bring to a boil. Wash outside of squash, cut squash in half and place in the stock pot of boiling water, flesh side down. Cover and boil for 15-20 minutes, until squash is tender. Drain squash. Holding halves with a potholder, use a fork to scoop out the stringy "spaghetti". Set aside. Melt butter in a sauce pan. Saute garlic and onions in butter til soft, then add spinach and squash. (The spinach and squash will soak up most of the butter. ) Sprinkle on flour and mix thoroughly. Slowly add milk, and stir til the sauce thickens. (It is kind of like making a basic white sauce.) Add in cheese and stir til melted. Serve and enjoy!
