In a large pot or Dutch oven, heat the olive oil over medium-high heat. Add the chopped onion and garlic, and sauté for 2-3 minutes until they become fragrant and translucent.
Add the ground turkey or beef to the pot and cook until browned, breaking it apart with a spoon as it cooks. If using beef, consider draining any excess fat.
Stir in the diced bell peppers and cook for another 3-4 minutes until they start to soften.
Add the diced tomatoes (with their juice), tomato sauce, low-sodium chicken or vegetable broth, Italian seasoning, dried basil, dried oregano, smoked paprika, salt, and pepper to the pot. Stir to combine.
If you’d like to add cauliflower rice for added nutrition and texture, include it in the pot at this point.
