Rinse green beans in a colander. Shake dry and lay out on paper towels to soak up any excess moisture.
Snip the tips off each end with kitchen sheers. You can leave the beans whole or cut them in half if they are too long.
Now is a great time to blanch the beans for 45 seconds in boiling water to bring out a vibrant green color! Drain immediately and soak in a bowl of ice water until completley cool. Drain again before tossing the beans in the olive oil and seasoning.
