Begin by cooking the orzo pasta: In a medium saucepan, bring the vegetable broth (or water) to a boil. Add the orzo and cook according to package instructions until al dente, usually about 8-10 minutes.
Once cooked, drain the orzo in a colander and rinse under cold water to halt the cooking process. Set aside to cool.
In a large mixing bowl, combine the cherry tomatoes, diced cucumber, bell pepper, red onion, and parsley.
In a small bowl, whisk together the olive oil, lemon juice, minced garlic, salt, and pepper until emulsified.
Add the cooled orzo pasta to the bowl with the vegetables. Pour the lemon garlic dressing over the mixture and toss everything together until well combined.
If desired, gently fold in the crumbled feta cheese for an added creamy texture and flavor.
Taste and adjust seasoning with extra salt, pepper, or lemon juice if necessary.
Cover and refrigerate the salad for at least 30 minutes to allow the flavors to meld.
Notes
Serve in a decorative bowl or individual cups, garnished with parsley and lemon wedges.
