Meanwhile, finely chop the pulp, then squeeze dry using a clean kitchen towel. Place in a medium bowl. Add cheese, all but 1 tablespoon scallions, half the bacon and the remaining 1/8 teaspoon each salt and pepper; stir to combine. Spoon the filling into the prebaked shells. Return to the oven and bake until the cheese is melted and the filling is hot, 12 to 15 minutes.
