While your beans are draining in the colander inside your sink, wipe your skillet dry with paper towel if you used it to steam your green beans. If you didn't just use it there is no need for paper towel!
Turn your heat to medium, add olive oil (and butter if desired) and wait until it shimmers or a drop of water flicked in it dances.
Add green beans to the large saucepan with the oil in it.
Cover, and cook for 2 minutes, stirring occasionally.
Add garlic and stir for another 30 seconds to a minute. You will be able to smell the garlic.
Add vinegar, honey, onion powder, salt and pepper.
Reduce heat to medium low. Stir regularly for a couple more minutes.
Serve immediately and enjoy!
