Slice jalapenos in half and remove seeds. Wear gloves or at least be super careful with what you touch. Don't touch your eye.
Place cream cheese and tuna in a mixing bowl. If you are using the real bacon pieces, add them now. Mix well.
Carefully place a small amount into each half of a jalapeno.
Place on a platter and top with the everything but the bagel seasoning, if desired. Store in fridge.
