toppings (optional )
1. Place a frying pan over heat and add the olive oil and onion. Cook for 5 minutes or until it begins to golden.
2. In a bowl, add the mince, herbs and beaten egg. Season with salt and pepper and add the onions. Mix well, then use your hands to shape into 4 even patties.
3. Cook the burgers on a preheated pan or barbecue for 5-6 minutes on one side. Flip the burger and while the second side is cooking, place a slice of cheese on top of the meat to slightly melt (optional).
4. Lightly toast the inside of the buns then add your toppings alongside any sauces you would like.
