Place the potatoes in a dry tea towel and squeeze to remove as much water as possible. Mix the potatoes with the salt and pepper in a large bowl. Heat the olive oil in a large sauté pan over medium heat until fragrant.
Using a 1/3 cup measure, scoop 1 measure of potato and place in the pan. Flatten with a spatula. Repeat 3 more times, making 4 pancakes. Divide the Boursin in four pieces and place one piece on each pancake. Sprinkle the chives evenly over the Boursin.
Scoop another 1/3 cup of grated potatoes and place on top of each pancake. Press down with a spatula, enclosing the cheese and the chives. Cook until the bottoms are golden, about 6 minutes. Turn the pancakes over and cook another 5-6 minutes or until the bottoms are golden. Serve immediately.
