wash and dry the vegetables, slice the carrots with a peeler (or grate them) and season them with the juice of an orange. Chop the salad leaves, peel the other orange, removing the white part. Prepare the dressing by mixing the yogurt, oil and a little salt. Compose the dishes by first putting the salad, then the carrots, a few slices of orange, chopped walnut kernels and finally, the yogurt sauce.
