Take out two mixing bowls. In the first bowl, add ground beef and pork. In another, put parmesan cheese, parsley, oregano, salt, pepper, and breadcrumbs. Gently mix the second bowl. When all the ingredients are “married”, add it into the first bowl and mix.
Form the mixture into adorable, bite-sized meatballs, about 1/2 inch in diameter.
Heat 1 Tbsp olive oil in a large non-stick skillet over medium-high heat. Add half of the meatballs and cook until browned, turning occasionally after 2 minutes to brown on all sides. Cook about 4 minutes total.
Transfer the cooked meatballs to a plate lined with paper towels to absorb any excess oil, while leaving the remaining oil in the skillet for the next batch. Once all the meatballs are all cooked and resting on paper towels, gently pat them to remove any excess oil. (Keep in mind that the meatballs won't be fully cooked at this point, but they will finish cooking in the soup.)
