Bring a large pot of salted water to a boil. Add the beans and cook for approximately 4 minutes. Drain the beans and run them under cold water. Set aside.

In a large pan over medium-low heat, add the olive oil and garlic, stirring frequently for 1 minute. Add the butter to the pan and then add the dates. Cook for approximately 3-4 minutes. Reduce the heat to low, season with salt and pepper and continue cooking, stirring often, about 6-7 minutes longer. Taste for seasoning.

Transfer the beans to a serving platter and serve right away.
