Turkey Tacos

"Heat 2 tablespoons of the olive oil in a large nonstick skillet over medium-high heat. Add the turkey and cook, while stirring and breaking up the meat with the back of a wooden spoon, until browned, about 3 minutes. Stir in the zucchini and onions, and saute until the veggies have started to soften, about 5 minutes more. Sprinkle the meat with the chili powder, cumin and paprika and give a good seasoning of salt and pepper; cook until fragrant. Stir in the chopped tomatoes and cook until the tomatoes have broken down and are soft, about 2 minutes more. Add the chicken broth and simmer lightly until the sauce is thickened and all the vegetables are tender, about 15 minutes."
