In a large frying pan over medium heat, brown the ground beef until no longer pink. Place in a large pot and do not drain.
In the same frying pan used for the ground beef, sauté the onion, celery and green pepper. Cook for about 5 minutes until the onion is translucent.
Add the sautéed veggies, kidney beans, mushrooms pieces, tomato soup and tomatoes with the liquid to the ground beef along with the seasonings, sugar, and garlic.
Stir all the ingredients well. Cover and simmer for one hour, stirring occasionally. Remove cover and simmer for 30 minutes or more, stirring occasionally. Taste and add more seasonings if desired.
Enjoy topped with sour-cream and shredded cheddar cheese.
