Sear the sausage: Heat 1 tbsp olive oil in a large pot over medium-high heat. Add sliced sausage and cook 3–4 minutes until browned. Remove and set aside, keeping the flavorful oil.
Brown the turkey: Add remaining olive oil and butter. Add ground turkey, season lightly, and let it brown undisturbed 3–4 minutes. Break apart and cook through. Remove and set aside, draining most liquid but leaving 1–2 tbsp for flavor.
Sauté the veggies: Add onion, bell pepper, Anaheim, and jalapeño. Sauté 5–6 minutes until softened and slightly browned. Add mushrooms; cook 2 more minutes. Stir in garlic and tomato paste, cooking 1–2 minutes until fragrant and caramelized.
Bloom the spices: Add chili powder, smoked paprika, cumin, oregano, cayenne, and crushed red pepper flakes. Stir 30 seconds to release oils and deepen flavor.
Build the base: Return turkey and sausage to the pot. Add crushed tomatoes, tomato sauce, chipotle peppers with adobo, broth, and salt. Stir well and bring to a simmer.
Simmer low and slow: Reduce heat to medium-low. Simmer uncovered 35–45 minutes, stirring occasionally. Add zucchini during the last 20 minutes and corn during the last 10–15 minutes.
Finish with brightness: Stir in lime juice. Taste and adjust — add more adobo for smoke, more salt for depth, or more broth if too thick.
Serve and garnish: Spoon into bowls and top with cilantro, shredded cheese, sour cream, or tortilla strips.
