For a spicier kick, use a hotter salsa or add a pinch of cayenne pepper to the squash mixture. Feel free to substitute the soy chorizo with regular chorizo, taco-seasoned ground beef, or even black beans for a different flavor profile. To save time, use pre-cubed butternut squash. You can also roast the squash a day ahead of time. A dollop of sour cream or Mexican crema adds a delightful coolness to the dish. For a richer flavor, use Monterey Jack or Oaxaca cheese in the enchiladas.
