Step 1

Using a sharp knife, lop off the top and bottom of the oranges so the oranges stand upright on a cutting board. Trim the rind and the white pith from them. Turn the oranges on their sides and very thinly slice them.

Step 2

Arrange the oranges on 4 plates. Top with the basil and onion and scatter with the olives. Place the greens on top. Drizzle each salad with a little oil. Let rest while you make the salmon.

Step 3

In a small bowl, mix together the chile powder, cumin, cinnamon, and salt. Pat the salmon dry and rub the spice mixture on the top side of each salmon fillet.

Step 4

Heat 1 tablespoon of the oil in a skillet. Add the salmon, spice side down, and cook 2 minutes over high heat. Turn and cook to the desired doneness, about 2 minutes longer for rare, depending on the thickness. Arrange a salmon fillet on each salad and drizzle with the remaining oil.
