Prepare all ingredients as instructed.
Heat the olive oil in a skillet over medium heat. Add the diced onion and bell pepper and cook for 3–4 minutes. Add the minced garlic and cook for 30 seconds.
Add the ground turkey, chili powder, ground cumin, smoked paprika, and black pepper. Saute breaking it up into smaller pieces until browned.
Transfer the cooked meat and vegetables to the slow cooker. Add the pumpkin, crushed tomatoes, beans, and chicken broth. Stir thoroughly to combine.
Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the chili is hot and the flavors have melded.
Combine the sparkling water, lemon, and chia seeds. Let stand for 5 minutes, then stir again. Add ice before serving if preferred.
Serve the chili with lemon chia sparkling water and pear slices.
