Pre-heat the oven to 375 degrees.
Make the biscuit dough by sifting together the flour, 3 tablespoons of the sugar, baking powder, baking soda and salt in a large bowl.
Using a pastry cutter or fork, cut in the butter until the mixture resembles course crumbs.
Make a well in the center, pour in the buttermilk and stir to combine until you have a dough ball.
Don't over-mix or your biscuits will be tough.
Wrap in plastic and refrigerate for at least 30 minutes.
While the dough is chilling, combine the blueberries, sugar, goat cheese, flour, thyme, lemon zest and salt in a large bowl.
Pour the mixture into a 9" pie plate and bake for 25 minutes.
Roll out the biscuit dough on a floured surface until it's about ½" thick.
Use a small (approx. 2") round cutter and place the dough rounds on top of the blueberry mixture.
Sprinkle on the remaining tablespoon of sugar, return to the oven and bake for an additional 25 minutes.
Serve warm with ice cream or Greek yogurt.
