This easy recipe for marinated gigante beans (also known as butter beans) is incredibly flavorful from olives, garlic, and red pepper. Sauteed on the stovetop, they're ready in 20 minutes. The giant white beans are creamy and meaty, and become infused with the robust flavor of the other ingredients. They're just like you find on the olive bar at the deli! Serve on toast with ricotta, in pasta, or as part of a charcuterie board.
