Combine all the ingredients except the oil in a large bowl. Mix, either by hand or with a spatula, until well combined and homogenous.
Portion the mixture into whole-walnut-sized balls, rolling to shape.
Heat the oil in a sauté pan over medium-high heat.
Place the meatballs in the hot oil and start to cook. After a minute or two, check to see if they are browned on the side touching the pan. If so, use an offset spatula or other thin tool (like a butterknife) to turn them to another side.
Once browned on the second side, you should be able to turn them and move them around by shaking the pan.
Start temping the meatballs all around the pan with your Thermapen ONE. Once the meatballs reach an internal temperature of 165°F (74°C), remove them from the pan. Thermapen ONE is fast enough that you can easily check every meatball. As the meatballs reach their pull temperature, remove them from the pan.
Serve them up with your favorite dipping sauce and reap the praise of your peers!
