Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a mixing bowl, combine the ground beef, ground pork, breadcrumbs, grated Parmesan, parsley, minced garlic, salt, pepper, and egg. Mix until well combined.
Form the mixture into small meatballs, about 1 inch in diameter, and place them on the prepared baking sheet.
Drizzle olive oil over the meatballs and bake in the preheated oven for about 15 minutes, or until cooked through.
While the meatballs are baking, heat a large pot over medium heat. Add the diced carrots and celery, cooking until they begin to soften, about 5-7 minutes.
Add the chicken broth to the pot, followed by the thyme, salt, and pepper. Bring to a boil.
Once boiling, add the small pasta and cook according to the package instructions until al dente.
Stir in the chopped kale and the baked meatballs. Cook for an additional 5 minutes until the kale is wilted and tender.
Serve hot, garnished with additional grated Parmesan cheese on top.
