Rinse the green beans. Snap off the tips and pull off the strings that run on both sides.
Heat a tablespoon of butter and olive oil in a frying pan. Spread the green beans in a single layer. Cook over medium heat for a minute. Sprinkle with salt and pepper. Stir a few times then spread in a single layer once more. Cook for another minute. Sprinkle with a little more salt and pepper, stir and spread the beans again and cook for another minute. Scoop out the beans and set aside.
Melt the remaining butter in the frying pan. Stir the garlic into the hot oil. Over medium-low heat, cook the garlic, with occasional stirring, until golden brown. Scoop out the garlic and set aside.
Add the lemon juice to the pan. Stir. Add the green beans back into the pan. Cook for one minute, stirring often.
Pile the cooked green beans on a plate. Pour whatever liquid remains in the pan over the beans. Spoon the toasted garlic on top of the beans. Drizzle with extra virgin olive oil and serve.
