Not a problem. For the Manicotti, you start first with the "crepes". Homemade are much lighter than storebought. And the recipe is very easy and can be scaled up in direct proportions. It will make about 12 crepes.
1 cup flour
1 cup seltzer
1 egg
1 Tbs. grated parmigianno cheese
1 Tbs. minced parsley
Mix all together and let stand at room temp for 1 hour. Then pre-heat a non-stick pan, wipe with some oil, and make the crepes, turning once. stack and cool until ready to use.
For a good all-purpose tomato sauce, again it can be scaled up.
3 Tbs. olive oil
1 medium onion diced fine
2 cloves garlic minced
1 28 oz. can crushed tomtoes
1 20 oz. can diced tomtatoes
5 basil leaves shredded
salt, pepper, and sugar to taste
Heat the oil and add the garlic and onion. cook for 3 minutes. Add the tomatoes, some salt and pepper. Bring to a boil, then reduce to a simmer. Simmer for 10-15 minutes, stirring once in a while. Stir in basil. cook for 5 minutes. Then you can do what you like.
For the manicotti filling, which can also be used ofr stuffed shells, lasagna, and ravioli also.
3# ricotta
1# shredded mozzarella
1 cup parmigianno cheese
1/2 cup minced parsley
3 eggs
1 tsp. ground pepper
Mix all together.
To assemble the manicotti. Pre-heat the oven to 350. Spoon enough sauce to cover the bottom of a baking dish. Spoon a few tablespoons of the filling onto a crepe and roll up. Place seam side down in the dish and repeat. Spoon a little sauce over the crepes and bake for 20-30 minutes until they bubble. Serve with extra sauce, cheese, and you can melt some mozzarella on top also.
Enjoy.
