Warm the pan: Heat a large, deep skillet or Dutch oven over medium heat. Add olive oil if using.
Brown the turkey: Add ground turkey.
Season with a pinch of salt and pepper. Cook, breaking it up with a spoon, until no longer pink, about 5–6 minutes.
Add aromatics: Stir in the onion and bell pepper. Cook until softened, about 4–5 minutes.
Add garlic and cook 30 seconds until fragrant.
Season it up: Sprinkle in the taco seasoning. Stir to coat the turkey and veggies so the spices toast lightly.
Build the sauce: Add diced tomatoes with chilies, tomato sauce, and chicken broth. Stir to combine and bring to a gentle simmer.
Add pasta: Stir in the dry pasta and corn.
Make sure the pasta is mostly submerged. Reduce heat to medium-low, cover, and cook 10–12 minutes, stirring every couple of minutes to prevent sticking. Add a splash more broth if the pan looks dry before the pasta is tender.
Beans and finish: When pasta is al dente, stir in black beans.
Simmer 1–2 minutes to warm through. Remove from heat.
Make it creamy: Let the mixture cool for 2 minutes, then stir in Greek yogurt until smooth. Fold in most of the cheese, reserving a little for topping.
Taste and adjust salt, pepper, and heat.
Serve: Sprinkle remaining cheese on top. Squeeze fresh lime over each serving and top with cilantro if you like.
