Spaghetti Squash with marinara sauce and chicken

If you love eating regular spaghetti then you're going to love this recipe!  It tastes just like regular spaghetti, but it doesn't have near as many calories!
Ingredients:  (Makes about 4 servings) 1 spaghetti squash, all natural no salt added tomato paste (6 oz.), 3 medium sized tomatoes, Italian seasonings, one garlic clove, half an onion, one celery stalk, and one carrot.
Cut the spaghetti squash in half and lay face down in a baking dish.  Spray the dish with olive oil before placing the squash in the dish.  Bake at 350 degrees uncovered for about an hour.  Check the squash by inserting a fork in it .  When it's soft then it's ready!  Meanwhile, dice the carrot, celery stalk, tomatoes, and onion.  Saute the veggies then mix in the tomato paste and Italian seasonings.  If you want chicken in your sauce then cook your chicken, and cut it up and mix it in with the sauce.  When the squash is ready turn it over and run a fork through it to make the spaghetti noodles.  Place the noodles on a dish and pour your sauce on top!  Enjoy!
