Salad: In a large mixing bowl, whisk together the extra virgin olive oil, red wine vinegar and salt and pepper. Toss in all the remaining ingredients and place to one side (toss now and then during if you can).
Prep Chicken: One by one, lay a chicken breast on a chopping board, then lay over a sheet of cling film. Use a rolling pin or mallet to pound the chicken. You want to get it nice and thin (or at least level thickness), but don't go overboard to the point it breaks apart.
Seasoning: In a small pot or bowl, combine 1 1/2 tsp oregano, 1 tsp salt and garlic powder and 1/2 tsp black pepper.
Coat Chicken: Line up 3 large shallow dishes or curved trays - the first with flour and half of the seasoning mixed in, the second with beaten egg and the third with Panko and the rest of the seasoning mixed in. One by one, take the chicken and carefully coat it in the flour, then the egg and finish in the Panko. Make sure you thoroughly coat the chicken at each stage.
Cook Chicken: Place a large pan over medium-high heat and fill with enough oil to comfortably cover the base of the pan. You want the oil hot enough that a crumb rapidly sizzles (I recommend using a thermometer and getting it to 180C/350F). One by one, fry the chicken for around 3-4 minutes on each side until golden and crispy. Timings will depend on how thick the chicken is (safe internal temp is 74C/165F for reference). Place on a wire rack with a tray or paper towels underneath and finish with a pinch of salt.
Serve: Spoon the salad over the chicken and finish with a good squeeze of lemon over everything. Tuck in and enjoy!
