In a large bowl, mix together the flour and yeast.
Add the warm water and olive oil to the dry ingredients and stir until a dough forms.
Add the salt, stuffing seasoning mix, and fresh herbs, mixing until just incorporated.
Knead the dough on a floured surface for about 5-7 minutes until it becomes smooth and elastic.
Place the dough in a lightly oiled bowl, cover, and let it rise for about 1 hour or until doubled in size.
Preheat your oven to 400°F (200°C).
Punch down the risen dough and transfer it to a greased baking sheet, shaping it into a flat rectangle or circle.
Let the dough rest for about 10 minutes, then make indentations with your fingers all over the surface.
Drizzle the dough with olive oil and sprinkle additional stuffing seasoning on top if desired.
Bake in the preheated oven for 20-25 minutes, or until golden brown.
Let the focaccia cool slightly before slicing and serving.
