Scratch a fork down the sides of the cucumber so it leaves deep grooves in the skin, then chop into erratic slices at an angle. Roughly chop the tomatoes, deseed and slice the pepper lengthways and add to a salad bowl with the chopped veg.
Destone the olives and tear into the bowl. Halve and finely slice the red onion (you can also try shaving it with a speed peeler), then add to the bowl along with a good drizzle of extra virgin olive oil, a good pinch of black pepper and a splash of red wine vinegar.
Toss everything together, then add a good squeeze of lemon juice. Break the feta in half and place on top, add a scattering of flowering oregano, drizzle over a little more extra virgin olive oil and pick over the mint leaves.
