Step 1Over a dish to catch the juice, cut the ends off each orange. Cut away the peel and slice each orange into three-eighths-inch crosswise slices, then cut each slice in half. Combine the sugar and cinnamon in a small bowl. Place the oranges in a large bowl and sprinkle with the sugar and cinnamon, stirring to coat.
Step 2Cut the dates into one-fourth-by-one-fourth-by-2-inch long strips, and add them to the oranges. Add the walnuts and orange flower water and gently stir to combine.
Step 3Place in a serving dish, and garnish with a few mint leaves. Chill well before serving.
