Prepare the oranges; slice off the tops and bottoms, then stand one of the oranges upright and slice off the skin from top to bottom; hold the orange in your hand and cut out the segments as close to the membrane as you can; catch the juices in a bowl and reserve
Arrange the salad leaves and most of the mint and thyme on a large platter, add the orange segments, the cherry tomatoes, avocado, olives and goat’s cheese; garnish with the remaining mint, thyme leaves and seeds
Mix together the olive oil and red wine vinegar and season with salt and pepper; add the reserved orange juice and whisk thoroughly; pour this dressing on the salad and serve immediately
