Preheat the oven to 350°F and prepare baking sheet. Line sheet with aluminum foil and place oven-proof wire rack over top. Spray with non-stick cooking spray.
Add all meatball ingredients to a large bowl. Gently mix with your hands until combined. Roll into about 3/4 inch meatballs. You should have about 25 meatballs. *See Note
Bake for about 15 minutes until lightly browned and cooked through. Set aside for later.
Soup
Meanwhile, start the soup. Heat the olive oil in a large pot or Dutch Oven over medium heat. Add the diced onions, carrots, and celery. Cook for about 7 minutes, stirring occasionally until the vegetables have softened. Add the garlic, stir, and cook for another minute.
Pour in the white wine, beef bone broth, chicken broth, bay leaf, white pepper, black pepper, and dry mustard. Bring to a boil.
Once boiling, add the ancini de pepe pasta. Cook for about 10 minutes until the pasta is almost cooked through, stirring occasionally. Lower the heat to a simmer and add the meatballs and arugula. Cook for another 3 minutes. Taste the soup and add salt and pepper as needed.
Divide among bowls to serve. Top with freshly grated parmesan cheese and cracked black pepper as desired.
