Cook the macaroni according to package directions. Drain and set aside.
In a skillet, add in ground beef and stir often to break it up. Cook for about 4 minutes and then add chopped onions and green pepper. Continue to cook until softened, about 5 more minutes. Add minced garlic and chili powder and stir to combine.
In the saucepan with the cooked macaroni, stir in diced tomatoes, tomato soup mixture, and drained kidney beans. Add in the ground beef mixture and stir to combine. Season with salt and pepper to taste.
Heat over medium-low heat until macaroni is thoroughly heated. Serve hot.
