Prepare the orzo. Bring a large pot of salted water to boil and cook the orzo according to the package instructions. When the orzo is done, drain it and run it under cold water to stop the cooking.
While the orzo cooks, prepare the dressing. Add the olive oil, red wine vinegar, lemon juice, garlic powder, dried herbs, red pepper flakes, and salt and pepper to a jar with a lid. Shake well to combine, then taste and adjust seasonings if needed. Store in the fridge until ready to use. Shake well before each use! If the oil hardens completely in the fridge, microwave for 10-15 seconds before use.
Prepare the salad ingredients. To a large bowl, add the cooked orzo, dressing, roasted red peppers, artichoke hearts, olives, tomatoes, chickpeas, salami, capers, mozzarella, basil, and kale (optional). Toss with tongs or two large spoons to combine all of the ingredients.
Separate the salad into your meal prep containers. Happy prepping!
