In a large bowl, stir together the flour, instant yeast, sugar, salt, and melted butter to form a sticky dough. Turn the dough out onto a floured surface and knead lightly to form a smooth ball. Coat the dough ball lightly with oil.
Cut parchment paper into an 8” circle. Place the dough ball on the parchment, then set it on the cooking pan. Transfer the cooking pan to the Slow Cook/Proof level.
Select the Proof program and adjust the temperature to 90°F / 32°C and the time to 30 minutes, then press Start.
Meanwhile, in a small bowl combine the softened butter, garlic, chives and salt. Mix well and set aside. Cut the mozzarella in thin (<1/4") slices, then cut the slices into 1/2" strips.
When the program is complete, carefully remove the cooking pan. Press the dough into an 8” circle (to match the parchment).
With a sharp knife, score the dough 8 times, then turn the dough 90 degrees and score 8 times again to form a crosshatch pattern. Spread the garlic butter evenly over the top.
Carefully insert pieces of mozzarella in each of the scored slots.
Select the Bake program and adjust the temperature to 350°F / 177°C and the time to 10 minutes, then press Start.
When the preheat cycle is complete, place the cooking pan in the Roast/Bake level. Close the oven to resume the program.
Bake until the cheese is melted and partially browned. Serve warm. The bread will easily pull apart at the scores.
