Meanwhile, roast the tomatoes by placing the tomato halves on a small, rimmed baking sheet then drizzle the olive oil on top and season with sea salt, freshly cracked black pepper, garlic powder, and crushed red pepper flakes, to taste.
Place into the oven and roast for 5 minutes, until softened a little bit. Remove from the oven and set aside to cool until room temperature.
Meanwhile, cook the orzo in a large saucepan of well-salted boiling water, per the package instructions.

Prepare the pasta salad by adding the eggplant, tomatoes, kalamata olives, feta crumbles, toasted pine nuts, fresh parsley, fresh dill, and the remaining well-shaken lemon vinaigrette and gently toss until evenly coated. Taste and re-season with sea salt and freshly cracked pepper, to taste, if needed.
