In a skillet, heat the oil over medium heat until simmering. Add the onion and cook until softened and nearly translucent, about 2 minutes. Add the garlic and cook until fragrant, 30 seconds.
Add the turkey and break up into crumbles using the back of a wooden spoon. Cook until no longer pink. Add the zucchini and chili seasoning. Stir to coat.
Transfer to a slow cooker, making sure to scrape in all of the caked on brown bits from the bottom of the skillet. Pour in the crushed tomatoes, tomato sauce, and beans. Stir to combine. Cover with the lid and cook on low for 7 hours.
Add the lime juice and season with salt and pepper to taste. Serve warm with suggested toppings.
