Spinach Spiral Bread

1. Prepare the Dough

In a large mixing bowl, combine warm water with instant yeast and let it rest for 5 minutes to activate the yeast. Gradually mix in flour and kosher salt, stirring with a wooden spoon until a dough forms. Transfer the dough to a lightly floured surface and knead until smooth and elastic. Place the dough in an olive-oil coated bowl, cover with plastic wrap, and let it rise in a warm place until it doubles in size.

2. Make the Spinach Filling

Soak raisins in red-wine vinegar. In a frying pan, heat olive oil and sauté yellow onion until caramelized. Add minced garlic and cook for another minute. Stir in the soaked raisins, baby spinach leaves, a pinch of kosher salt, black pepper, red-pepper flakes, and toasted walnuts. Cook until the spinach is wilted and well combined. Allow to cool.

3. Prepare the Oven and Baking Sheet

Preheat your oven to 400°F (205°C) and line a baking sheet with parchment paper.

4. Assemble the Bread

On a lightly floured surface, roll out the risen dough into a rectangle. Spread the cooled spinach filling over the dough, leaving a border. Optionally, mix feta cheese with sour cream and spread over the spinach filling. Roll the dough into a tight log and place seam side down on the baking sheet. Brush with beaten egg.
