Step 1
Preheat the oven to 400 degrees. Cut the spaghetti squash in half and remove the seeds. Lightly spray the squash with cooking spray and sprinkle with salt and pepper. Place cut side down on a baking sheet lined with parchment paper. Roast 35-45 minutes until tender.
Step 2
While the squash cooks, prepare the filling. Heat a skillet over medium-high heat. Add the oil. Once hot, add the peppers and onions. Cook for 6-8 minutes until tender and crisp. Add the chicken, black beans, and taco seasoning. Stir well and cook for about 1-2 minutes. Taste and adjust the seasoning if needed.
Step 5
Add this mixture back to the empty spaghetti squash halves. Drizzle with extra enchiladas sauce and top with cheese. Bake for 10-15 minutes until the cheese is melted and bubbling. Garnish with cilantro, green onions, and any other enchilada toppings you enjoy.
