The Martha-Jacque onion sandwich with my own spin

So I made the sandwhich I shared the other day with the Martha video.

On one piece of bread, I used margarine/butter, the other piece I put McCormick’s Mexican Mayonesa. Salt and pepper. And it needed a cut of the richness so I used my handy dandy vinegar spritzer and spritzing some white vinegar on the onions before salting, and I let it sit for a bit so the vinegar could do it’s magic.

AMAZING
