In a large pot or Dutch oven, heat the olive oil over medium-high heat and add the onions. Cook until softened.
Add the ground meat to the onions and season with the chili powder and garlic powder. Continue cooking until the meat is browned and cooked through.
To the pot, add the tomatoes with their juices, the kidney beans, chicken broth, and the packets of chili seasoning mix. Stir the chili and bring to a boil.
Add 2 cups of elbow macaroni to the pot and simmer the pasta until tender-about 15 minutes. Stir often to prevent sticking. Turn down the heat if the chili mac is bubbling too furiously. Note: If your chili is drying up as the macaroni cooks, add more water or broth.
Once the pasta is al dente, turn off the heat and serve with a generous heap of grated cheddar cheese.
