Creating Supreme Focaccia Pizza can be straightforward if you follow these simple steps:

1. Prepare the Yeast: In a small bowl, combine warm water and yeast. Let it sit for about 5-10 minutes until frothy.
2. Mix Dry Ingredients: In a large mixing bowl, whisk together the flour, salt, garlic powder, and dried rosemary.
3. Combine Mixtures: Pour the activated yeast mixture and ¼ cup of olive oil into the dry ingredients. Stir until a dough begins to form.
4. Knead the Dough: Transfer the dough onto a floured surface. Knead for about 5-7 minutes until smooth and elastic.
5. First Rise: Place the dough in a lightly oiled bowl, cover with a cloth, and let it rise in a warm place for about 1 hour, or until doubled in size.
6. Preheat the Oven: While the dough is rising, preheat your oven to 425°F (220°C).
7. Prepare the Pan: Grease a large baking sheet or pizza stone with olive oil.
8. Shape the Dough: Once the dough has risen, punch it down and transfer it to the prepared pan. Stretch and press the dough to fit the pan.
9. Add Toppings: Use your fingers to create dimples in the dough. Drizzle with olive oil, sprinkle with sea salt, and add mozzarella and Parmesan cheese. Layer your assorted toppings over the cheese.
10. Second Rise: Cover the topped dough with a cloth and let it rise for an additional 20-30 minutes.
11. Bake: Place the pan in the preheated oven and bake for 25-30 minutes, or until golden brown and cooked through.
12. Cool and Serve: Remove from the oven and let it cool for a few minutes. Garnish with fresh basil if desired and slice into squares or wedges.
