Heat a large skillet with 1 tablespoon of olive oil over medium heat. Add the sliced mushrooms and pinch of salt and sauté until browned and somewhat softened, about 5 minutes.

Add the remaining tablespoon of oil to the pan, and add the asparagus and leek. Cook for 2-3 minutes until the asparagus is crisp tender, then add the peas and garlic and cook 30 seconds longer. Place the cooked vegetables in a bowl and set aside.

Add the stock or water to the pot and scrape any bits from the bottom of the pan. Add the pasta and stir. Bring to a boil, then add the cream. Reduce the heat to medium low and cook at a high simmer until the pasta is tender, about 10-12 minutes depending on the type of pasta used. If the liquid has evaporated and the pasta is not done yet, add up to a 1/2 cup more liquid and continue cooking. Add the vegetables back to pot during the last 30 seconds of cooking to warm them through.

When the pasta is done, remove from heat and stir in the lemon zest, juice, parmesan cheese and fresh basil. Taste and add salt and pepper, to taste. Serve with additional parmesan cheese as desired and enjoy!
