This is a summer staple for us, simple and sweet and has been around forever. I use it on Hot/chili dogs, burgers, grilled chicken, chicken salad, tuna salad sammies, hoagies....Uhh you can see where I am going with this!! It keeps for up to a week but doesn't last that long at mi casa. You can also adjust the recipe for the ammt of servings you need, but do not underestemate, as my Husband piles it high LOL.
sweet onions ( i prefer vidalia) chopped
regular yellow mustard
3 - 4 Tbsp
white table sugar ( adjust to taste)
