01 - Bring 6 cups water and 1 tsp salt to a rolling boil in a large pot. Add orzo pasta and cook according to package directions until al dente, typically 8-10 minutes. Drain thoroughly, reserving 1/2 cup of the starchy cooking water. Set aside.
02 - Heat olive oil in a large skillet over medium heat. Add minced garlic and sauté for about 1 minute until fragrant and lightly golden, being careful not to burn.
03 - Add diced zucchini, cherry tomatoes, yellow bell pepper, asparagus pieces, and peas to the skillet. Cook for 4-5 minutes, stirring occasionally, until vegetables are tender-crisp and vibrant in color.
04 - Add the cooked orzo to the skillet with the sautéed vegetables. Pour in the reserved pasta water and add grated Parmesan, lemon zest, and lemon juice. Toss everything together until the cheese melts into a light, creamy coating that clings to the pasta and vegetables.
05 - Remove from heat. Season with salt and black pepper to taste. Stir in chopped fresh basil and parsley until evenly distributed. Adjust seasoning if needed.
06 - Transfer to serving bowls or plates. Top with additional grated Parmesan and fresh herbs if desired. Serve immediately while hot.
