Preheat the broiler. Line a rimmed baking sheet with foil. Combine the ground turkey, ricotta, pesto, parmesan, 1/2 teaspoon salt and a few grinds of pepper in a large bowl. Mix with your hands until just combined. Form into 24 small meatballs (about 1 tablespoon each); transfer to the prepared baking sheet. Broil until lightly browned, 5 to 7 minutes.
Meanwhile, heat the olive oil in a medium Dutch oven or pot over medium-high heat. Add the onion, garlic, Italian seasoning and 1/2 teaspoon salt. Cook, stirring, until the onion is softened, about 3 minutes. Stir in the chicken broth, 2 cups water, the escarole and ditalini. Cover and bring to a boil, then partially uncover and reduce the heat to maintain a gentle simmer. Cook until the pasta is al dente, about 10 minutes.
Add the meatballs and simmer, uncovered, until warmed through, about 3 minutes. Season with salt and pepper. Drizzle each serving with olive oil and sprinkle with parmesan and parsley.
