Heat 1 tbsp coconut oil over medium heat in a large, deep skillet. Add in the cubed chicken pieces, sprinkle with salt and pepper, and cook for 5-7 minutes, stirring occasionally. Remove the chicken from the pan and set it aside. It's ok if it's not fully cooked through - it will finish cooking in the sauce.
Next, add the remaining 1 tbsp coconut oil to the pan along with the onion, garlic, red bell pepper, carrots, and ginger. Sauté over medium heat for 5 minutes.
Add in the red curry paste and stir until fragrant.
To make the sauce, add in the pumpkin puree, coconut aminos, coriander, turmeric, salt, and coconut milk. Stir. Add the chicken back into the pan and stir. Let everything simmer over medium heat, stirring occasionally, for 8-10 minutes.
Add in the broccoli florets and cook for an additional 5 minutes, until they are bright green and tender.
Serve the pumpkin red curry chicken as-is or over jasmine rice or cauliflower rice, and top with cashews and fresh cilantro, if desired. Enjoy!
