"Create a very high-protein, high-fiber focaccia with a very bubbly, sourdough-like texture using these ingredients: vital wheat gluten, regular wheat flour, soy protein isolate, polenta flour, rye flour, coconut sugar, dry yeast, water, olive oil, sun-dried tomatoes in oil, olives, fresh basil. Use metric units. Aim for a focaccia with an airy, open crumb, strong hydration, long fermentation or preferment-style flavor development if possible, and a crisp olive-oil crust. Include practical steps and toppings using the listed ingredients. If needed, balance the dough so it remains workable despite the added protein powders."
