Cook the bacon in a large, deep skillet over medium-high heat, stirring occasionally, until partially cooked but not brown, 5 to 6 minutes; drain on paper towels.
Combine the drained bacon, green beans, and pears in a large saucepan; pour enough water over the mixture to cover. Bring to a boil; reduce the heat to low and simmer until cooked and tender, about 30 minutes.
Remove from the pan to a serving dish with a slotted spoon, draining excess water. Season with salt and pepper to serve.
