In a large saucepan, brown the ground turkey over medium heat. Drain well and put turkey on a plate lined with paper towels.
Add the olive oil and onion and green pepper to the saucepan. Cook over medium heat for several minutes until the onions and peppers begin to soften.
Add the garlic and cook for another minute.
Add the turkey back in along with all the remaining ingredients, except for the toppings.
Bring to a boil and then reduce heat to medium low and simmer for an hour.
Enjoy with shredded cheese and sour cream.
