Cook the orzo in salted water until al dente. (I usually cook it one minute less than the package recommends) Drain well.
½ cup orzo pasta
Heat some olive oil in a medium skillet over medium heat. Add the onion and cook, stirring for 3-5 minutes, until the onion is softened and slightly brown. Add the cooked salmon and warm it in the pan, breaking it up into flakes with your spoon.
¼ cup red onion, 8 ounce salmon fillet
Add the spinach and stir in the skillet for a minute or two until the spinach has wilted. Add the orzo and stir to combine. Remove skillet from heat.
5 ounces baby spinach, ½ cup orzo pasta
In a small cup, whisk the lemon juice, 2 tablespoons olive oil, salt and pepper to make the dressing.
2 tablespoons lemon juice, 2 tablespoons olive oil, ⅛ teaspoon salt, ⅛ teaspoon black pepper
Add the tomatoes, dill, Kalamata olives, feta cheese, and dressing to the skillet and stir to evenly distribute.
½ cup cherry tomatoes, ¼ cup pitted Kalamata olives, 2 tablespoons chopped fresh dill, ½ cup feta cheese
This salmon orzo salad can be served right away, at room temperature, or cold.
