Add the water, egg, olive oil, honey, all-purpose flour, bread flour, and instant yeast to the bowl of your Ooni Halo Pro mixer.
Mix at 15% speed for 30 seconds. Increase to 25% speed and mix for 2 minutes. Let the dough rest for 10 minutes.
Add the salt. Mix at 35% speed for 5 minutes, then increase to 45% speed and mix for another 4 to 5 minutes, or until the dough is smooth and passes the windowpane test.
Transfer the dough to a lightly oiled container. Cover and let rise for about 3 to 3½ hours, or until the dough has noticeably increased in size. The exact time will depend on the temperature of your kitchen.
Divide the dough into 8 equal pieces, about 124 to 125 grams each.
Shape each piece into a smooth ball and place on a parchment-lined baking sheet.
Cover loosely and let proof for 45 to 60 minutes, or until the rolls are puffy.
Preheat the oven to 375°F.
Brush the tops with egg wash.
Bake for 18 to 22 minutes, or until golden brown and the internal temperature reaches 190°F to 200°F.
Cool on a wire rack before slicing and serving.
