Combine ricotta, eggs, grated cheese, salt, pepper and spinach. When well mixed, start filling empty shells. Remember Nicole, I would get you girls to fill with a teaspoon!!! These days I use a piping bag. (Once filled, the cannelloni should be cooked immediately)
To bake, cover the base of a baking dish with sauce. Arrange cannelloni side by side on top of the sauce in a single layer. Cover with remaining sauce.
Cover dish with alfoil and bake in a moderate oven for approximately 30 minutes. Do not let sauce dry out but make sure that the pasta is cooked by inserting a skewer to test.
To serve, sprinkle with grated parmesan cheese.
(Note: In place of cannelloni shells, pancakes can be used)
