I like to replace traditional pasta with quinoa, brown rice, beans (garbanzo, black, any!), and spaghetti squash. My tips are to watch the servings with quinoa, it looks like extremely small beads and always makes me want to add more than an appropriate serving. I also prefer to boil my spaghetti squash when I cook it even though it loses a little nutritional value. I prefer boiling because I can season the water and give the squash a bit more flavor.
