Pour warm water, sugar, and yeast into a big mixing bowl.
Let it sit for five minutes to let the yeast bubble and get going.
Add the bread flour, all-purpose flour, salt, and olive oil.
Mix everything together with a sturdy spoon or your hands until you get a sticky dough.
Knead the dough on a lightly floured surface for about ten minutes.
Stop when the dough feels smooth, stretchy, and just a bit tacky.
Move the dough to a greased bowl.
Cover it with a towel and let it rise somewhere warm for about an hour, or until it doubles.
Punch the dough down to get rid of extra air.
Split it in half and shape each piece into a long, thin loaf.
Set the loaves on a parchment-lined baking sheet.
Preheat your oven to 400°F.
Let the loaves rise for 15 to 20 minutes while the oven heats up.
Bake for 18 to 20 minutes, until the tops are light golden and sound hollow when you tap them.
Let them cool a bit, then slice and use for sandwiches.
