  • To prepare the squash; Cut the squash from stem to end and scoop out the seeds. Place the squash halves cut-side-down onto a rimmed baking sheet lined with parchment paper.

  • For the casserole; Using a large oven-proof skillet heat the cream with cream cheese over medium heat until the cheese has melted. Add garlic, cumin, chili powder, jalapeno and tomatoes and simmer for 1 minute
  • Add green onions, 1 1/2 cups cheddar cheese, black beans, parsley, spaghetti squash, and season with salt and pepper. Mix to combine. Top with remaining 1/2 cup of cheese
  • Place the skillet in the oven and bake at 375 F for 15 - 20 minutes until the cheese is bubbling. Rest for 10 minutes before serving. If desired, add your favourite toppings
