Filling
In the Ziplock bag, start by adding the melted unsalted butter.
Add the ground beef, the eggs, the grated carrot, the grated potato, the diced red bell pepper, the grated onion, the crushed garlic cloves, the cream cheese, the grated mozzarella cheese and the grated cheddar cheese.
Season with the salt, a pinch of black pepper and mix everything very well until combined.
Then transfer this meat mixture to the egg carton and spread it evenly.
Next, make holes in the meat using an egg as a guide.
In a medium bowl, add the grated mozzarella cheese, parsley to taste and mix to incorporate.
Fill the holes we made in the beef placed in the egg carton with this cheese mixture, add the processed cheese on top of everything and close the egg carton tightly.
Place it in the freezer and let it chill for at least 1 hour.
After this time has passed, remove from the egg carton and cut into smaller pieces.
Next, place them in a large skillet over medium to low heat with hot vegetable oil and let them fry until golden brown.
Serve.
