Add oil to a large soup pot and heat to medium-high heat. Once hot, add onions and bell pepper. Sauté until onion is translucent, approximately 3 minutes. Add minced garlic and sauté until golden, about 1 minute.
Add the ground turkey, using your spatula to crumble it. Sauté the meat, stirring occasionally, until no longer pink.
Add in all other ingredients. Stir to combine. Simmer for 15 to 20 minutes. Taste and add extra salt if desired.
