Well, not exactly all of them. The pan held about 30 and there are a few more left in the strainer. And I bought three boxes because I used three boxes of manicotti noodles. So the one box I actually used would have been enough.
I tweaked the recipe a little and it is a good thing as I still used all the stuffing. The sauce part of the recipe always seems not enough, but it covers sparingly. Maybe I will make my own sauce recipe next time to have 'enough'.
I still need to make the potatoes and carrots as well as the poast pork. The brownies are fantastic and as I was putting them away in the freezer I saw the rolls, good thing, too. They are thawing nicely on the counter.
