Snap off the stems of the beans and remove their strings, if any. Fill a large saucepan with water and bring it to a boil. Add the green beans and cook for 3 to 4 minutes to blanch. Drain the beans again, then transfer to a medium bowl and set aside.

In a medium saute pan, cook the bacon over high heat until crispy. Remove the bacon with a slotted spoon, reserving the bacon drippings, and transfer the bacon to paper towels to drain. Decrease the heat to medium-high. Add the onion and garlic to the pan and saute until fragrant, about 2 minutes. Add the sherry and cook until about 1 tablespoon of liquid remains. Add the beans, cumin, pepper, salt, and bacon and toss well.

Place the beans on a serving platter and serve immediately.
