Before starting, preheat the oven to 450°F. Wash and dry all produce. Add 6 cups water and 1 tsp salt to a large pot (use same for 4 ppl). Cover and bring to a boil over high heat. Add orzo to the boiling water. Cook uncovered, stirring occasionally, until tender, 6-8 min.

While water comes to a boil, pat salmon dry with paper towels. Season with half the Lemon-Pepper Seasoning and salt. Arrange salmon on a lightly-oiled, foil-lined baking sheet. Drizzle 2 tsp oil (dbl for 4 ppl) over top. Roast in the middle of the oven until salmon is cooked through, 7-10 min.**

While salmon roasts, cut tomato into 1/2-inch pieces. Roughly chop spinach. Roughly chop parsley. Add spinach, tomatoes, tzatziki, half the parsley and remaining Lemon-Pepper Seasoning to a large bowl. Drain, then roughly chop olives.

When orzo is tender, reserve 2 tbsp pasta water (dbl for 4 ppl), then drain orzo well. Add orzo and reserved pasta water to the large bowl with spinach-tzatziki mixture. Season with salt, then stir to combine.

Divide orzo salad between plates. Top with olives, if desired, then salmon. Sprinkle remaining parsley and feta over top.
