Mix yeast with 1 & 1/2 cups of warm water and set aside until ready.
Combine all the dry ingredients: all-purpose flour, bread flour, salt, garlic powder, and dried oregano in a large mixing bowl (or stand-mixer's bowl).
Add the honey, olive oil, and yeast mixture.
Mix and knead until you get a smooth dough, then place it in an oiled bowl.
Cover the bread dough with a clean kitchen towel and set aside until it doubles in size.
Lightly dust your countertop with flour, and divide the dough into two equal portions.
Roll each portion (no particular shape or size) and place the chopped kalamata olives on top.
Roll the dough back, knead it gently and form it into a ball.
Use a sharp knife to cut a cross on top of the kalamata bread dough, then place it on a tray lined with parchment paper.
Cover with a kitchen towel and set aside until it doubles. (This generally takes me 30 to 45 minutes.)
Preheat oven to 200°C (375°F).
Brush your olive bread with water --- use a pastry brush.
Place the baking tray in the lower part of the oven for 30 to 35 minutes; or until it turns golden.
Set aside for about 20 minutes.
Your kalamata olive bread is now ready for slicing and serving!
