    1. Hi Janet,
      I think that would be delicious but I would suggest just wrapping the bacon around it from the start. If, the bacon starts to brown too quick, just tent loosely with foil.

    1. Hi Bonnie,
      You can use any combination of vegetables like bell peppers or a combination of cheese and breadcrumbs would work. I hope this helps.
