In this Southern Italian–inspired one-pot pasta, a thick tuna steak cooks to moist perfection at the same time as the penne, cherry tomatoes, and olives. When the cooking is done, break up the tuna into large flakes with a spoon and mix it into the pasta. The sauce will look thin at first glance, but it thickens into a beautiful, clingy sauce upon standing. The following recipes are excerpted from INSTANT POT® ITALIAN © 2018 by Ivy Manning.
