Grease an 8x8” pan with some olive oil or non-stick spray around the sides and on the bottom.
In a small bowl, combine the yeast, sugar, and ½ cup warm water. Stir then set aside for 10 minutes to activate. If it does not foam and smell like yeast, start over.
In another small bowl, stir together the psyllium husk and ⅔ cup warm water. Set aside to thicken for 10 minutes.
In the bowl of a stand mixer, gently whisk together the tapioca starch, millet flour, sorghum flour, baking powder, xanthan gum, and salt. Make a well in the middle and pour in the olive oil, applesauce, yeast mixture, and psyllium gel mixture.
Fix the stand mixer with the dough hook and mix on low speed until all the dry ingredients are incorporated. Then increase to medium speed for 2-3 minutes. The dough will be very sticky and will not fully wrap around the hook.
Turn the dough out onto a floured surface. Use any of the gluten free flours. Flour your hands and divide the dough into 9 pieces of even weight, about 80g each. If the dough is too sticky to handle, you can refrigerate it for 1 hour to firm up.
Take a piece of dough and press it flat with your fingers. Pick up each of the edges towards the middle to form a ball, then flip it upside down and use both hands to gently turn and smooth the dough ball.
Repeat with the remaining dough and place into the greased pan.
Cover the pan with plastic wrap or a kitchen towel and set in a warm place to proof for 1 - 1½ hours until doubled in size. In the winter, I like to preheat my oven to 100ºF then turn it off, creating a nice warm space. Ensure to move the rolls before you preheat the oven.
Preheat the oven to 375ºF. Brush the tops of the rolls with olive oil and sprinkle with salt.
Bake uncovered for 22-25 minutes until the tops are golden.
Remove from the oven and brush with a touch more olive oil. Allow to cool for at least 15 minutes. They are delicious when served warm, but the texture will benefit from cooling slightly. Enjoy with dairy-free butter, jam, or spreads.
