Preheat the oven to 210 degrees and line an oven tray with baking paper.
Sift the flour and salt together in a large bowl before rubbing in the butter until the mixture is the consistency of bread crumbs.
Slowly add the milk and use a butter knife to combine. Turn out the dough and knead until it forms a smooth ball.
Use a rolling pin to roll dough out until you have a 30 x 40cm rectangle.
Spread the softened butter over the dough, leaving a 2cm gap around the edges.
Sprinkle the baby spinach leaves, feta cheese and ⅔ of the grated tasty cheese over the top of the butter.
Starting at the long side carefully roll the dough until enclosed.
Place the scroll log into the fridge for 20 mins to chill.
Cut into 12 slices – approximately 2cm thick and sprinkle the remaining grated cheese over the top of the scrolls.
Place on a baking tray, making sure you leave enough room to rise and bake in oven for 20 minutes or until golden brown on top and cooked through.
Let the scrolls cool on the tray for 5 minutes and then enjoy!
