  1. I’m seeing comments about a BURN notice and the FB post where I found the recipe references BURN notices. Anyway to avoid this error message?

  2. Could I make this with an Alfredo based sauce or would it be too thick? Would the shells stick to the bottom without a thick layer of meat sauce to place the shells on top of?

    1. Its up to your choice to use the Alfredo sauce instead of marinara sauce. But definitely it would be a new taste.
