Mix the butter and flour until like breadcrumbs. Slowly add in water to bind all together.
Let it rest
The filling
In the meantime cook the spinach with a drizzle of oil
Once cooked (mince if you want) add together with ricotta, egg and grated cheese.
Then roll out the dough, roll out the filling and create a roll, cut it and put it in the stove, cook 15 minutes, turn them after the first 5 minutes.
Let it cool down and enjoy it
Notes
You can also add a basic tomato sauce (maybe leftover pasta sauce) over the top, and add some extra grated cheese for a really extravagent dish.You may need to cook in batches if they are not packed tightly in the Omnia oven (they may take longer to cook if more in the oven though!)
