Brown the ground turkey in a nonstick skillet over medium heat, cooking for about 7-10 minutes. Stir occasionally until it s no longer pink, then let it cool slightly before mixing.
Combine in a large bowl: shred the cooked spaghetti squash, add the ground turkey, chopped bell peppers, drained corn, black beans, green chiles, diced tomatoes with juices, enchilada sauce, and spices. Mix until everything is well-coated and combined.
Transfer the mixture to a greased 9 13 inch casserole dish. Sprinkle the reserved cheese evenly on top, creating a beautiful layer for that gooey finish!
Cover the dish with foil and bake for 45 minutes. Then, remove the foil and bake for an additional 15 minutes until the cheese is bubbly and slightly golden.
