Bring a large pot of salted water to a rolling boil and cook the Banza pasta for 7-9 minutes until al dente, then drain and set aside.
Pat the chicken breast dry and season both sides with the sea salt and black pepper.
Heat the olive oil in a large skillet over medium-high heat and sear the chicken for 5-6 minutes per side until golden brown and cooked through.
Remove the chicken to a plate to rest, then lower the skillet heat to medium and add the diced yellow onion, sautéing until translucent.
Add the minced garlic and cook for 30 seconds until fragrant, then pour in the chicken broth to deglaze the pan, scraping up any browned bits.
Stir in the heavy whipping cream and grated parmesan cheese, whisking constantly until the sauce is smooth and slightly thickened.
Slice the rested chicken into bite-sized pieces and add it back to the skillet along with the cooked pasta, tossing thoroughly to coat in the creamy sauce.
Garnish the dish with chopped fresh parsley and serve immediately.
