Cut aluminum foil into eight 6 X 6-inch squares of foil and then set aside.
Arrange the foil sheets on a rimmed baking sheet in a single layer, then set aside.
Use a Microplane to shred the Parmigiano Reggiano cheese and also shred the Fontina cheese and place it into a bowl.
Add the mayonnaise to the cheese and pepper, and then stir together well.
In a large bowl, measure and then add the flour, sugar, salt, baking powder and baking soda, whisk well to combine.
Using a box shredder, grate the cold butter into the flour mixture and then stir well to combine, to the consistency of peas.
Add the buttermilk and stir it well into the flour mixture until the dough comes together.
Sprinkle flour onto a clean countertop and then turn out the dough onto the countertop, sprinkling extra flour onto the top.
Fold the dough over onto itself four times, then knead the dough gently trying not to overwork it. Additionally, incorporate more flour as needed to keep the dough from sticking to the countertop.
Work the surface of the dough until it is a 10-inch square that is 1/2 inch thick.
Then, using a pizza cutter, cut the dough into sixteen 2-inch squares.
Spray each foil sheet with non-stick spray and then place 1 dough square into the center of each foil sheet.
Top each biscuit with 2-3 tablespoons of the cheese mixture, making sure to gently spread it over the dough.
On top of the cheese, place 1 tablespoon of the Little Green Dress, then without pressing down, gently spread the mixture around the cheese.
Top each with the remaining biscuits and then fold up the foil corners making sure to NOT press the biscuits down at all, just gently place them on the LGD.
Bake the Gas Station Biscuits for 22 to 25 minutes in the middle rack of the oven, or until they are browned slightly.
