I think the recipe came from the back of the box of manicotti. Have been making this recipe for years. I like to add some herbs to the tomato sauce just to spice it up a little. you can crumble the bread in a food processor. just pulse a few times.
Recipe came from a friend a long, long time ago. Can be made ahead of time and kept in the fridge. The servings all depend on the size of the buns and how much you put on them. The mixture looks awful but tastes delicious. I didn't have a can of tomato sauce in the cupboard so I wasn't sure of the size (8 to 10 ounce size maybe?).
Recipe is the one Mom has been making since we were little kids. I don't know where she got the recipe from but it's the only one I have ever used. There are a lot of ingredients but it really is simple to make.
Found the recipe on a recipe website but can't remember which one. This recipe is very rich. You can have this recipe on the table in about an hour or less. I have never paid attention to how long it takes to make
