In a deep mixing bowl, add in the spinach, egg, ricotta, parmigiana cheese, mozzarella, and a pinch of
sea salt and black pepper. Mix all together and
scoop a couple of tablespoons onto each cooked lasagne sheet. Spread the
stuffing over each sheet and then begin rolling the lasagna. If extra
stuffing comes out when you are rolling, remove and add to a lasagne sheet that has fewer
stuffing.
