Kale, Chorizo, and Manchego Stromboli

1. In a large bowl, mix the water, yeast, olive oil, and sugar. Let sit for 5 minutes until foamy.
2. Add 2 cups of flour to the water mixture and stir to combine. Add remaining flour 1/4 cup at a time until flour is incorporated and dough is slightly sticky – you may not need all three cups of flour. Turn dough out onto floured surface and knead for 5 minutes.
3. Spray another large bowl with cooking spray, place dough in bowl, cover with plastic wrap and set aside for at least an hour and a half. (I have let the dough sit for up to about 8 hours).
4. Preheat oven to 375F and line a baking sheet with parchment paper. Heat oil in a large Dutch oven over medium heat. Add chorizo and cook until browned, about 7 minutes. Remove chorizo with a slotted spoon and place on a paper towel-lined plate. Leave behind oil in Dutch oven.
5. Add onion and a pinch of salt to Dutch oven and cook over medium heat for about 5 to 7 minutes, until it starts to brown. Add garlic and cumin and cook for about 1 minute, until fragrant. Add half of kale, until it just starts to wilt. Add remainder of kale, water, stock, and cover pot. Cook over medium heat for 15 minutes covered. Remove lid, increase heat to high, and continue to cook until liquid is gone and kale is tender, about 15 to 20 minutes. Add chorizo and stir to combine. Let cool.
6. Beat egg and water in a small bowl.
7. Divide dough in half and roll out into two 10 x 14 inch rectangles. Brush 1/2 inch of edges all around with egg wash. Evenly spread half of the cheese and half the kale mixture onto dough, roll into a cylinder, and pinch edges to seal. Transfer to baking sheets, brush the tops with egg wash, and bake for 35 minutes, until browned. Let cool for about 5 minutes before slicing.
