This recipe is super versatile and customizable, where you can change out the herbs to your liking or whatever you have on hand. soaking the bread crumbs helps ensure the meatballs stay moist so I wouldn't recommend skipping that part but you can use a nondairy milk, broth, or even water. Feel free to use fresh or dried herbs, whatever is easiest to find. The size of the meatball does not matter but you may need to adjust the cooking time if your meatballs are larger to cook them longer or if they are smaller they can cook for less time as long as the internal temperature reads 165 degrees F.
