Penne with asparagus, mushrooms, and carrots

I love vegetables. I also love pasta. So this dish is a perfect storm of what I love. John sautéed the mushrooms, onions, and garlic in a little olive oil. Two minutes before the penne was done I added the carrots and asparagus stalks to the boiling water. With a minute to go, in went the asparagus tips. Drain. Combine the penne and veg in the mushroom pan. Add a little reserved pasta water. Serve topped with green onions and a little very good olive oil. Bliss.
