Squeeze excess liquid from the soaked roll. Peel the garlic and press it through a garlic press. Finely chop the parsley.
In a large bowl, combine the minced meat, squeezed roll, egg, diced onion, sheep cheese, pressed garlic, and chopped parsley. Season with salt and pepper, then knead the mixture until smooth and well combined.
Shape the mixture into meatballs roughly the size of golf balls, using damp hands to prevent sticking.
Heat oil in a large frying pan over medium-high heat for about 2 minutes until shimmering.
Carefully add the meatballs to the hot oil and fry for 8–10 minutes, turning occasionally, until golden brown and cooked through.
