Meanwhile, in a small (8-inch) saute pan over medium-low heat, heat 1 1/2 tablespoons of olive oil, add the garlic, and cook for 1 minute, until fragrant but not browned. Add the panko, tossing to coat in the oil. Cook over medium-low heat for 3 to 4 minutes, until the panko is golden brown, tossing occasionally. Off the heat, add the pine nuts and lemon zest.
