01 - Heat olive oil in a large, deep skillet or Dutch oven over medium heat. Add sliced leek and minced garlic, sauté until softened, approximately 2 minutes.
02 - Add pasta, vegetable broth, and water to the skillet. Bring to a boil while stirring, 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 reaches al dente texture and vegetables are tender-crisp. Most liquid should be absorbed.
04 - Add spinach, cherry tomatoes, lemon zest, lemon juice, and grated Parmesan. Cook for 2 minutes until spinach wilts and tomatoes are heated through, creating a light sauce.
05 - Remove from heat. Season generously with salt and freshly ground black pepper. Sprinkle with chopped fresh herbs and additional Parmesan. Serve immediately while hot, offering lemon wedges on the side.
