In the bowl of your stand mixer, combine water, yeast, and sugar. Let it sit for 5-10 minutes, or until the yeast blooms.
Add in the salt, olive oil, and flour, mixing until combined. (Add additional flour if needed, or until the dough pulls away from the sides of the bowl.)
Switch to the dough hook and knead on medium speed for about 5 minutes.
Round the dough into a ball and place it into a greased bowl to rise (about 1 hour, or until doubled in size).
Line two large baking sheets with parchment paper.
Gently punch down on the risen dough to deflate it. Divide the dough into 12 equal balls by dividing the dough in half until you are down to 12 pieces.
Roll each ball of dough into a rope (about nine inches), and place it on the prepared baking sheets. Cover the dough ropes with a clean kitchen towel. Allow the dough to rise in a warm place for about 1 hour.
When the dough is just about done rising, preheat the oven to 425°F.
Bake for 12-15 minutes, or until golden brown. Brush them with the melted butter and sprinkle with the garlic salt and kosher salt. Serve warm.
