Deliciously Cooked Fresh Flat Beans

Growing flat green beans (also known as Italian beans or green romano beans) in the garden is an absolute must for our family. From the very first harvest until the last, every single bean is consumed and enjoyed. The best part is being able to use the whole bean pod without removing any of the individual beans inside.

One of our favorite ways to prepare fresh flat beans is by cooking them within a fresh tomato and vegetable butter sauce. The beans can also be cooked ahead of time in boiling water for 10 minutes before adding them to the prepared tomato sauce.
