In a large pot over medium-high heat, heat about half the olive oil and then cook the carrot, celery, onion, and garlic and cook until they start to soften, 5-8 minutes, and season with salt and pepper.
Add the rest of the olive oil then add the turkey and cook until no longer pink.
Add tomatoes to the pot, crushing them with the back of a wooden spoon, reduce the heat until just simmering and cook for 20 minutes.
Stir in basil and balsamic vinegar and season to taste with salt and pepper.
