Lightly grease a 9x13" baking pan with oil.
Squeeze any excess water out of the spinach (if using fresh spinach, see notes below). Combine all the filling ingredients together and mix thoroughly in a bowl until combined.
Use a rolling pin to roll the dough into a large rectangle about 16x12", then spread the filling in an even layer over the dough.
Starting from one long edge, roll the dough up tightly into a log. Use a sharp knife to slice the log into 12 even pieces. Place each piece cut-side up on a lined baking tray, they will expand!
Let rise in a warm place for 30 minutes.
Preheat the oven to 380℉/190℃. Once the oven is hot, bake the scrolls for 20-25 minutes, until the edges are golden. Remove and let cool before serving!
