When my SIL told me about this recipe I was very skeptical - I'm not a big mayonnaise fan and the thought of hot mayonnaise just wanted to make me retch (I know I probably shouldn't say that when describing a recipe, but it just sounded plain nasty. I decided to be a mature adult and at least try it (holding my nose the whole time). Well - let me tell you something. You could have knocked me over with a feather and they had to knock me away from the dish in order for other people to get some. This is delicious. My favorite part is after all the inside has been eaten you put it back in the oven to let the bread crisp up some more and then just start tearing chunks of bread off & eating it. It is divine. This is so easy and people will think you are a gourmet chef. Pict-Sweet Seasoning Blend is frozen chopped onions, celery, red and green pepper mixture found in the frozen vegetable section. The stores in my area usually have the Hawaiian bread in the deli section of the store.
