01 - Heat olive oil in a large, deep skillet or Dutch oven over medium heat. Add sliced leek and minced garlic, sauté until softened and fragrant, approximately 2 minutes.
02 - Add pasta, vegetable broth, and water to the skillet. Bring to a boil, stir well to combine, then reduce heat to maintain a gentle simmer. Cook for 8 minutes, stirring occasionally to prevent sticking.
03 - Stir in asparagus pieces, sugar snap peas, and sliced zucchini. Continue cooking for 7 minutes, stirring frequently, until pasta is al dente, vegetables are tender-crisp, and most of the liquid has been absorbed.
04 - Add spinach, halved cherry tomatoes, lemon zest, lemon juice, and grated Parmesan. Stir gently and cook for 2 additional minutes until spinach wilts and tomatoes are heated through.
05 - Remove from heat. Season generously with salt and freshly ground black pepper to taste. Sprinkle with chopped fresh herbs and additional Parmesan cheese if desired. Serve immediately.
06 - For enhanced presentation, garnish with extra fresh herbs and lemon wedges on the side for guests to adjust acidity to preference.
