Step 1
Preheat oven to 350°F. Cut spaghetti squash in half lengthwise. Scrape out and discard seeds and membranes. Place halves, cut side down, in a large baking dish; add water. Bake at 350°F for 45 to 50 minutes or until tender. Remove squash from oven. Turn cut side up; cool for 10 minutes. Scrape inside of squash with a fork to remove spaghetti-like strands.
Step 2
Heat oil in a medium skillet over medium-high. Add onion and garlic; sauté 4 minutes. Add chickpeas, thyme, and tomatoes; cook 1 minute. Add spaghetti squash, spinach, and salt; toss gently to combine. Cook 2 minutes or until spinach is just wilted. Sprinkle with cheese.
