Step 1

Bring a large pot of salted water to a boil. Cook the orzo according to package directions. Drain and set aside.

Step 2

Add the dried oregano, garlic powder, onion powder, 1/2 teaspoon salt, 1/2 teaspoon pepper and 1/2 cup of the olive oil to a large bowl. Whisk to combine, then add all the prepped vegetables. Toss the vegetables to coat them in the marinade.

Step 3

Heat a grill pan over medium-high heat. Once the pan is heated, add the vegetables in batches, being sure to keep them in a single layer and not to overcrowd the pan. Grill until the vegetables have nice char marks and are beginning to soften, 2 to 3 minutes. Flip the vegetables and cook for an additional 2 to 3 minutes. Remove to a rimmed baking sheet. Keep grilling until all the vegetables are cooked. Cool slightly, then cut the vegetables into small bite size pieces. Save any leftover marinade to build the dressing for the salad.

Step 4

To the serving bowl with the leftover marinade from the vegetables, add the lemon zest, lemon juice, Dijon mustard, 1/2 teaspoon salt, 1/2 teaspoon pepper and the remaining 1/4 cup olive oil. Whisk to combine. Add the cooked orzo and the chopped grilled vegetables and toss to combine. Add the feta, parsley and dill and toss again. Season with salt and pepper to taste.

Step 5

Serve immediately or keep at room temperature until ready to serve.
