• Lightly grease a baking tray with olive oil.
• Optional step - Pour the oil in a frying pan and fry the onion over a medium heat until soft, add the garlic and cook for another minute then place to one side to cool.
• In a large bowl, mash the beef mince with a fork to break it down. Stir through the cooled/raw onions and garlic, beetroot, egg, ground cumin, ground coriander, Worcester sauce and salt and pepper, mixing until well combined.
• With wet hands, take a small handful of the mixture – slightly larger than golf ball size – and shape into a ball. Place on the greased tray and flatten to around 2cm thick.
• Once all burgers have been shaped, drizzle over a little more oil, then cover with clingfilm and place in fridge for at least 30 minutes to firm up.

To Oven Bake:

• Heat the oven to 220˚C / 425˚F.
• Take the clingfilm off the burgers and place the tray in the oven for 10-15 minutes or until the burgers are cooked through.
• Serve in a bun with avocado, lettuce and tomato – or any combination you or your child eat!

To Barbecue:

• Heat the barbecue and cook for 3-4 minutes each side until cooked through.
