To hard boil the eggs: bring a large pot of water to a rolling boil. Gently add the eggs and cook them for exactly 12 minutes, then place them directly into an ice bath until cool. Peel the eggs and slice them in half using a sharp knife. Scoop the egg yolks into a bowl, being careful to leave the whites in tact.
Preheat the broiler.
Mash together the egg yolks, greek yogurt, Boursin cheese, salt and pepper. Scoop the mixture back into the egg whites.
Sprinkle the breadcrumbs evenly over the eggs and place them under the broiler. Toast the breadcrumbs, watching carefully to make sure they don't burn, approximately 2-3 minutes.
