Get your oven ready by putting a rack in the middle and warming it to 350°F (175°C). Cover a baking tray with foil.

Cut mozzarella into small cubes and pop it in the fridge while you work on the meat.
03 -
Beat the eggs in a big bowl. Throw in ground almonds, Worcestershire, powdered onion, sea salt, powdered garlic, and pepper. Mix it up. Add your meat and blend with your hands just enough to mix it all together. Don't handle it too much.
04 -
Take about two-thirds of your meat blend and form a rough 9x5-inch loaf on your foil-lined tray. Make a hollow space in the middle about 7x3 inches, keeping a 1-inch meat border all around.
05 -
Dump your cold cheese cubes evenly inside the hollow. Top with your leftover meat mixture, pushing down to make it flat and totally covering the cheese inside.
06 -
Cook until it's nicely browned and the middle hits at least 165°F (74°C) on a food thermometer. This'll take around 55 to 60 minutes.
07 -
Let it sit for 15 minutes before cutting. This lets the juices settle and the cheese firm up a bit.
