Preheat the oven to 400 F. Prepare a large baking sheet with parchment paper. Add the cubed butternut squash. Bake 20 minutes. Remove from the oven and set aside.
Preheat a large skillet to medium heat. Add the olive oil, diced bell pepper and jalapeño. Cook 3 minutes then add the ground turkey. Break up the ground turkey as it cooks with a spatula. Cook 5-7 minutes until browned.
Add the butternut squash to the skillet with the spinach, cumin, paprika and salt. Stir to combine. Cook a few more minutes until the spinach is wilted. Serve immediately with optional toppings.
