Cook the orzo according to the package directions in well-salted water.
Drain and transfer the cooked orzo to a large mixing bowl.
In a small bowl or measuring cup, whisk together the lemon juice, olive oil, honey, salt, oregano, garlic powder, and black pepper until well combined.
Pour the dressing over the warm orzo and toss to coat.
Add the cucumber, cherry tomatoes, red onion, chopped basil, and crumbled feta.
Gently stir until everything is evenly combined.
Serve immediately, or refrigerate for at least 30 minutes before serving for an even more refreshing pasta salad.
