Preheat the oven to 230 °C/ 450 °F.
Dice the mozzarella in 20-25 equal sized pieces.
Place it in the freezer for 30-60 minutes.
Freezing the cheese will prevent it from leaking out while baking.
Place the meat, egg, minced garlic, thyme, oregano, ...
...
almond flour, salt and pepper into a bowl.
Mix until well combined using your hands or a mixer.
Divide the meat into 20-25 pieces (I made 20).
Remove the cheese from the freezer.
Take each piece and flatten using your hands.
Place a piece of the mozzarella cheese in the middle and fold the meat over it.
Briefly roll between hands and place on a baking tray lined with parchment paper or a non-stick baking mat.
Place in the oven and bake for 13-15 minutes.
Meanwhile, prepare the Marinara Sauce.
Place the marinara sauce in a large pan and heat up over a medium heat.
The first time I made this recipe, I used too much marinara sauce (photo below) which I then used to make another batch of meatballs.
Take the meatballs from the oven and place in the pan with marinara sauce.
Using a spoon or a spatula, cover with the sauce from all sides.
Drain the olives (I used both green and black Kalamata olives).
Insert a toothpick into each olive and then into each meatball.
Garnish with freshly chopped basil and enjoy! Tip: You can serve the marinara sauce separately from the meatballs by dipping into it.
