Bring a pot of salted water to a boil and cook the chickpea pasta according to package directions until al dente.
While pasta cooks, heat olive oil in a large skillet over medium-high heat and add the sliced chicken breast and andouille sausage.
Season the meat with sea salt, black pepper, and half of the Cajun seasoning, searing until browned and cooked through.
Remove meat from the skillet and add the diced bell pepper, red onion, and minced garlic, sautéing until the vegetables are tender-crisp.
Pour in the chicken broth and remaining Cajun seasoning, scraping the bottom of the pan to release the flavorful browned bits.
Reduce heat to low, stir in the Greek yogurt until smooth, then toss in the cooked pasta and meat until thoroughly coated.
Garnish with fresh parsley and serve immediately while the sauce is creamy and warm.
