How to Make Braised Flat Beans
Step #1: Heat two tablespoons of olive oil in a large non-stick skillet (for which you have a lid) over medium-high heat. Once the oil is shimmering, add the onions and season generously with salt. Fry the onions until they are turning golden brown, about 4 to 6 minutes. Step #2: Turn the heat down to medium and add the garlic and canned tomatoes. Fill the empty tomato can halfway up with water and pour it into the pan. Step #3: Stir well, then add the flat beans to the pan. Cover and simmer for 20 minutes, stirring occasionally. Step #4: Stir the balsamic vinegar into the sauce. Continue cooking, partially covered, for another 20 to 30 minutes or until the beans are very tender and have lost their squeak. Step #5: Fold the olives into the mixture along with the remaining tablespoon of oil. Taste and sprinkle with salt and freshly ground black pepper as desired.
