Heat a Dutch oven or large pot until warm, then add the olive oil and onions, and cook until onions are just soft

Step 2

Add the chicken to the pot, then add the Italian seasoning, sea salt, garlic powder and pepper, and cook over medium high heat until chicken is no longer pink, stirring frequently

Step 3

Stir in the pasta, marinara sauce and water, then cover with lid, and cook until pasta starts to soften, stirring frequently to make sure pasta doesn't stick to the bottom
