Heat olive oil in a large pot over medium-heat. Add onions and garlic and stir for 1-2 minutes. Once the onions are translucent, slowly pour in the chicken stock. Then stir in the corn starch and stir until it is completely dissolved.
Next stir in the elbow noodles, tomatoes, bacon & chive seasoning, salt and pepper. Bring to a boil and then cover the pot and bring the heat down to low. Allow to cook for about 10 minutes, or until the noodles are cooked.
Once the noodles are cooked, stir in the cheese and bacon. Garnish with chives, if desired. Enjoy while it’s hot!
