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, 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 zucchini slices. 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 additional minutes until spinach wilts and tomatoes are heated through. Season generously with salt and black pepper.
05 - Remove from heat immediately. Garnish with chopped fresh herbs and additional Parmesan cheese. Serve hot while vegetables retain their vibrant color. Offer lemon wedges on the side if desired.
