In a large oven-safe skillet, heat olive oil over medium heat.
Add onion and cook 2–3 minutes until softened
Stir in garlic, sweet potatoes, and bell pepper. Cook for 6–8 minutes, stirring occasionally, until sweet potatoes are just fork tender.
Stir in black beans, shredded chicken, enchilada sauce, cumin, paprika, salt, and pepper.
Reduce heat to low, cover, and let it simmer for 8–10 minutes, stirring often, until bubbling and everything is warmed through.
Stir in spinach or kale if using, until wilted
Garnish with green onions or cilantro and serve straight from the skillet with tortillas, avocado, or lime wedges on the side. Enjoy!
