  • Preheat the oven to 425ºF. Cut the squash in half, lengthwise and put them face down in a baking dish. Add enough water to cover the squash by 1/4". Roast squash for 20 minutes.
  • While the squash is cooking, add the remaining ingredients (minus the cheese) into a saucepan. Start with just 1/2 cup of water and add more as needed. Bring the pot to boil, then reduce and simmer until thickened, about 10 - 15 minutes. 
  • Once squash is done roasting, remove from oven, flip over and scoop out the seeds. Fill each squash half with about 1 cup of sauce. Sprinkle with cheese.
  • Place the squash back into the oven and turn the oven to broil. Broil for 2 - 3 minutes, watching carefully so the cheese doesn't burn.
  • Remove and serve immediately!
