1 teaspoon chopped fresh oregano, or 1/4 teaspoon dried oregano
Snap the ends off the beans. If they are very young, leave the beans whole; if large, break the beans into 2-inch lengths. Place the beans in a saucepan; add 1 cup water and the onion, garlic, salt, and pepper.
Cover and bring to a boil; reduce the heat to a simmer, and cook about 8 minutes, until the beans are crisp-tender; drain.
Sprinkle the sunflower seeds and oregano over the beans. Toss lightly to mix.
