Heat the olive oil in a large pot over medium-low heat. Add the onions, peppers and garlic with a pinch of salt and pepper. Cook until softened, about 5 minutes.
Add in the ground turkey and another pinch of salt and pepper. Break it apart with a wooden spoon and brown it, about 6 to 8 minutes. Once the meat is browned, add in the chili powder, paprika, oregano, cumin and red pepper flakes. Stir and cook for 2 minutes.
Add in the tomatoes, beans, stock and maple syrup. Bring the mixture to a boil then reduce it to a simmer. Cover and simmer for 20 to 30 minutes. Serve with tortilla chips, avocado, sour cream or whatever you love on your chili!
