I love the way that the asparagus mimics the shape of the penne in this super easy pasta dish. While the water gets to boiling I prep onion, garlic, and the asparagus. Once the pasta goes in the water to cook for 10 minutes I heat up some olive oil and sauté the onion and garlic. A few minutes before the pasta is done I add the asparagus. Once the pasta is drained it joins the vegetables. I stir them around a bit and add some pasta water to make a light sauce. After serving you might like to garnish it with a drizzle of olive oil and some grated Parmesan cheese.
