This recipe for 
Penne with Roasted Asparagus from Food & Wine popped up on my Facebook page yesterday and looked perfect for a quick dinner after baseball practice.  I added grilled chicken and a spinach/strawberry/goat cheese salad.  I liked it. My nine-year old thought he 'liked the usual pasta sauce' better but ate the chicken and asparagus.  Worth a try.
 Penne with Roasted Asparagus and Balsamic Butter 
 
Simmering the balsamic vinegar both mellows and thickens it. When  tossed with the hot pasta and the butter, it forms a smooth, uniquely  flavored sauce.
 
 Ingredients 
1 pound asparagus1 tablespoon olive oil
2 teaspoons salt
1/2 teaspoon fresh-ground black pepper
1/2 cup plus 2 tablespoons balsamic vinegar
1/2 teaspoon brown sugar
1 pound penne
1/4  pound butter, cut into pieces  (I used about 3 Tblsp and it was plenty)
1/3 cup grated Parmesan cheese, plus more for serving  
  Directions 
-  Heat the oven to 400°. Snap the tough ends off the asparagus and discard  them. Cut the spears into 1-inch pieces. Put the asparagus on a baking  sheet and toss with the oil and 1/4 teaspoon each of the salt and  pepper. Roast until tender, about 10 minutes. 
-  Meanwhile, put the vinegar in a small saucepan. Simmer until 3  tablespoons remain. Stir in the brown sugar and the remaining 1/4  teaspoon pepper. Remove from the heat. 
-  Cook the penne in a large pot of boiling, salted water until just done,  about 13 minutes. Drain the pasta and toss with the butter, vinegar,  asparagus, Parmesan, and the remaining 1 3/4 teaspoons salt. Serve with  additional Parmesan.
