Boil the orzo as instructed in lightly salted water. Drain, rinse and set aside.
Heat water in a large pot of salted water, immerse the broccoli for about one minute (with the lid on), just until it brightens and becomes slightly tender. Drain, rinse and set aside to cool somewhat.
To make the pesto, combine 2 cups of the broccoli, garlic, most of the pine nuts, parmesan, 1/4 tsp salt, and juice from half the lemon in a food processor or blender. Pulse the broccoli, drizzling in the olive oil and the crème fraîche until well blended.
To assemble, just before serving, combine the orzo and broccoli. Pour over 2/3?s of the pesto (keep the remaining for another day). Squeeze the other half of the lemon over all. Sprinkle with the remaining pine nuts and add the chopped olives and cilantro. Stir to mix well and serve.
