I adapted this recipe from one I found on the A Year of Slow Cooking blog. It works remarkably well, with the meatballs even getting a little brown, at least the ones on top. My no-salt seasoning contained onion powder, garlic powder, and other things. I found it to be a bit spicy, and might reduce the quantity next time, or use rosemary or Italian herbs. Please pay attention to comment on how long to cook. The originator suggested you can double or even triple the recipe, but I have not tried that.
