Combine all the ingredients and mix until the ingredients are just combined, taking care not to over mix (this can cause the meatballs to be very dense).
To mix the meatballs: With wet hands (this prevents the meat from sticking to your hands), form meatballs of approximately 3cm/1in and place on a chopping board.
To fry the meatballs: pre-heat a non-stick frying pan and add a tablespoon of olive oil. Fry the meatballs in batches until golden brown on both sides and cooked through.
To bake the meatballs: Pre-heat the oven to 220ºC. Line 2 baking sheets with baking/parchment paper and add the meatballs, keeping some space between them. Drizzle the meatballs with 1-2 tbsp olive oil and place in the oven. Allow to bake, turning over halfway, until golden brown and cooked through (approximately 20-30 minutes).
Remove the meatballs from the heat, drizzle with lemon juice (optional) and serve.
