The easiest way to stretch 3 ounces of pasta into a really satisfying meal is to add a lot of vegetables. Ahead of the pasta getting cooked I sautéed 8 ounces of mushrooms and a big handful of asparagus spears cut into bite-sized pieces. When the pasta was cooked I added it to the veg along with some pasta water, a little butter, and olive oil. It was a tasty and enjoyable dinner for two.
