Using a large, sharp knife, pierce a spaghetti squash in several places. Place the spaghetti squash in a glass baking dish and cook in the microwave on high for 10-15 minutes, turning the squash halfway through cooking. The cooking time will depend on the strength of your microwave. When pressed, the skin should be soft enough to depress slightly, but not so soft that it’s collapsing.
Before handling, let the squash stand for 10 minutes. Cut it in half lengthwise and scrape out the seeds and fibers. Using a fork, twist out strands of the spaghetti squash flesh and place in a large bowl. Cover and chill.
Add pecans, apples, and green onions, and stir well.
Toss with the dressing. Serve.
In a small bowl, whisk together olive oil, vinegar, agave nectar and salt.
