Add all the ingredients into a large bowl and mix well with your hands
If you sprinkle everything over the meat evenly it makes mixing easier.
Cooking
Add 2 tablespoons of olive oil and 1 tablespoon of butter to a large skillet and heat on medium-high heat.
Sear all the sides of the meatballs and then turn the heat down to medium and cook, turning often until the meatballs are cooked through. The internal temperature should be 160°
Work in batches as you don't want the meatballs to be crowded in the skillet.
Let the meatballs cool
Flash Freezing
Place the meatballs on a parchment-lined baking sheet. Put into the freezer for about 2 hours.
Once the meatballs are frozen transfer them to a container of your choice for storage in the freezer.
