We love taco night...we love bbq night...let's just be real..we love food. So one of our favorite little add-ons to dinner has been our pickled red onions.
Just slice one red onion super thin..I use my mandolin. Season liberally with salt. Cover with red wine vinegar and wait. (A couple hours or overnight) I have also added a clove of garlic finely diced and it is yummy!
