Preheat oven to 425 degrees.

Add the ground pork, ground beef, fresh herbs, onion, garlic, spices, salt, and pepper to a large mixing bowl. Mix everything until well combined.

Scoop the meat mixture using a cookie dough scoop to form the meatballs and roll them between your hands. Place them on a sheet pan drizzled with olive oil.

Bake the meatballs at 425 degrees for 15-20 minutes or until the internal temperature reaches 165 degrees Fahrenheit.

While the meatballs are cooking, make the tzatziki sauce by adding the cucumber, garlic, and dill to a food processor and pulse until finely chopped.

Add the cucumber mixture to the Greek yogurt and stir until well combined. Stir in the lemon juice and salt and store in the fridge until ready to serve.

When the meatballs are done, let them cool slightly and serve with the tzatziki sauce.
