Vegan "Pancit Bihon" with Spaghetti Squash

Preheat oven to 400 degrees F.

Place spaghetti squash halves cut-side down on a baking sheet. Bake until tender, 35 to 40 minutes. When cool enough to handle, remove the flesh by scraping with a fork. Set the flesh aside (discard the shells).

Heat oil in a large wok or large skillet over medium-high heat. Add onion, garlic and ginger; cook, stirring, until the onion is translucent, about 3 minutes. Add mushrooms; cook, stirring, until soft, 3 to 5 minutes. Add green vegetables, carrot, salt and pepper; cook, stirring, until softened, 1 to 2 minutes. Remove from heat and stir in the spaghetti squash and soy sauce. Serve with lemon wedges, if desired.
