Warm up a big skillet over medium heat and cook the sausage, breaking it apart as it cooks until it turns brown. Toss the flour over the sausage bits and stir it around, letting it cook for 2 minutes. Pour the milk in little by little, giving it a good stir the whole time. Turn up the heat a bit and wait for it to start bubbling. Then turn it back down and let it simmer about 5 minutes until the gravy thickens. Toss in the salt, black pepper, and sage.

Roll out one puff pastry sheet and carefully press it into the bottom of a 9-inch pie pan, letting a little hang over the edges. Pour the gravy with sausage into the lined pan and spread it evenly. Roll out the second pastry sheet and lay it over the top. Trim off any extra bits, press the edges to seal, and poke a few tiny holes in the top to let out steam.
