Heat olive oil in a large pot over medium-high heat, add the chicken, sprinkle with Cajun seasoning, and cook until browned, about 5 minutes
Remove chicken and set aside
In the same pot, add the onion, bell pepper, and garlic
Sauté for 2-3 minutes until softened
Add the pasta, chicken broth, and half-and-half
Stir and bring to a simmer, cover and cook for 10-12 minutes, stirring occasionally, until the pasta is tender
Stir in the diced tomatoes, cooked chicken, Greek yogurt (or cottage cheese), and Parmesan cheese, and mix until creamy
Season with salt and pepper to taste and garnish with fresh parsley or green onions!
Enjoy!!!
