Yoplait brand Nouriche

Question

Rabbi, First of all thank you for all the work you did for us and all readers this passover. I really appreciate someone who not only says yes or no, but can back up the answer. Too often when asking my local rabbi, I would be told "Yes you can, but we don't." We want answers, and you give them to us straight.
