In a French oven, heat oil on medium high and cook ground turkey for a few minutes or until it starts to brown.
Add garlic, onion, jalapeno peppers and sweet peppers. Cook for five more minutes or until veggies start to wilt.
Add salsa, canned tomatoes, water and chili powder to the pan. Reduce heat to low and stir. Cover the pan and simmer for 30 minutes while stirring occasionally. More water can be added if a thinner chili is desired.
Serve with sour cream and shredded cheddar cheese if desired.
