Pre-heat oven at 200˚C / 392˚F. Prepare the eggplant: slice off the ends, then cut into rounds, about ½ cm thick. Slice each round in half to create half-moons. Toss with olive oil, season with salt and pepper, then spread over a baking tray lined with baking paper. Bake for around 25 minutes. Use tongs to toss periodically to ensure they cook evenly. Eggplant will shrink and turn golden once ready.
Rinse lentils well under running water, then add to a pot, cover with water (ample water), bring to a boil and let simmer until soft, about 20 minutes. Drain and set aside. See my notes re soaking the lentils in advance for optimal nutrition and digestion.
Once the eggplant has cooked, remove and set aside. Place cherry tomatoes and walnuts on a tray and bake until the tomatoes are shrivelled and juicy. You’ll need to take the walnuts out after about 5 minutes as they toast up quite quickly – once they're done, roughly chop.
In a large bowl, combine eggplant, lentils, tomatoes, walnuts, capers, preserved lemons (sliced thin) and finely chopped parsley.
Whisk all dressing ingredients together and pour over salad, toss. To serve, add a couple of drops of lemon essential oil to coconut yoghurt, mix well, and add a dollop with your meal.
