01 -  In a large mixing bowl, combine all-purpose flour, instant yeast, fine sea salt, and granulated sugar. Stir in olive oil and warm water until a soft dough is achieved. If needed, add additional water one tablespoon at a time. 
 02 -  Knead the dough on a lightly floured surface for 5 minutes until smooth and elastic. Transfer to an oiled bowl, cover, and allow to rest for 15 minutes. 
 03 -  Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper. 
 04 -  Roll out the dough to a 10x6-inch rectangle or oval. Position the shaped dough on the parchment-lined baking sheet. 
 05 -  Brush the surface of the dough with 1 tablespoon olive oil. Evenly distribute cranberries and walnuts over the top. Sprinkle with flaky sea salt. 
 06 -  Place in the oven and bake for 15 to 18 minutes, or until the edges are golden and the flatbread is cooked through. 
 07 -  Remove from oven. Drizzle with honey. Top with crumbled goat cheese and fresh rosemary, if desired. Let cool briefly, slice, and serve warm.
