Rinse and trim the green beans and throw them in a large pot. Add just enough water to cover them, then bring them to a boil over high heat. Once at a boil, lower the heat and let them simmer until they are as tender as you'd like them to be. Then drain them into a colander.

Add the olive oil to the pot. Once it's hot, add the garlic and cook and stir just until it's fragrant. Then add the green beans back to the pot with the seasonings and vinegar and toss to coat them evenly. Taste and add more seasonings or more vinegar to taste if needed. Then serve.
