Heat 2 cups of water with 4 tablespoons of olive oil in the microwave until lukewarm.
In a large bowl combine 3 cups of flour, yeast, salt, sugar and stir well.
Stir the warm liquids into the flour mixture with a wooden spoon, mixing well.
Stir in another cup of flour until combined.
Transfer the dough to a well floured work surface and knead for a few minutes while working in the remaining cup of flour a bit at a time, just until the dough is soft and smooth.
Grease a large bowl with oil and place your pizza dough in the greased bowl while turning the dough over to grease all over.
Cover the bowl with a dish towel and set aside to rise for 60 minutes or until doubled in size.
Line 2 baking sheets with parchment paper and brush lightly with olive oil
Once the dough has doubled in size, transfer to a floured work surface and divide into 4 equal portions.
Transfer the portions to the prepared baking sheets, placing 2 on each sheet allowing enough space between the 2 portions.
Using your hands, push the dough towards the edges of the baking sheet while shaping it roughly to a 6x8 rectangle.
Cover with a clean dishcloth and allow to rest for 30 minutes.
Preheat oven to 400 degrees F.
Uncover the focaccia dough and using your fingers press down to form indentations.
Stir together 4 tablespoons of olive oil with the minced garlic, oregano and brush over the surface of the focaccia.
Bake for 20 to 25 minutes or until golden brown.
