Prepare all your ingredients and set them aside in bowls. Dice both onions and split in half. One half will be set aside in a bowl while the other half will be cooked with the minced steak.
In a big pan drizzle extra virgin olive oil and add 1/2 of your diced onion, followed by the crushed garlic and give it all a good mix. fry on a medium heat until soft (2-3 minutes)
Add your minced steak to the onions and garlic. Using the back of a fork break the meat down until there are no chunks/lumps. This might take a few minutes but don't be tempted to make do. My Mum is keen on this step. She adds a drizzle of water to help break the meat down.
Once broken down you will continue to cook your meat for 4-5 minutes. Add your oregano. At this stage I seperate a bit for the children.
Add the chopped chilli and season the meat, give it a good mix and continue to cook on a medium heat. Meanwhile grill yout pitta breads.
I quite like it when the meat gets a little bit charred in parts. This typically happens when you leave the meat on a low heat for longer, say an extra 10 minutes. If you are in a rush you can stick to the recipe and serve as soon as the meat is cooked.
Add lemon juice and salt to your onions. Then add your dried chilli flakes and salt to your tomatoes.
