This is a super easy, quick, and delicious dinner. In the time it takes to boil the water and cook the pasta, I have sautéed half an onion in olive oil along with garlic powder, red pepper flakes, and oregano. With five minutes left on the pasta cook I add the broccoli to the onions and cook the florets until crisp/tender. I put chunks of tuna from a drained can in with the broccoli and onions and then spill the drained penne on top. After adding additional olive oil and some pasta water I carefully stir trying not to break up the chunks of tuna. A grating of Parmesan is all that is needed to complete the dish.
