Notes

Use whichever vinegar you like. I like a combination of white vinegar or apple cider and lime juice.  You can use more lime juice than vinegar if you prefer it.
Cut the onions into whatever shape you like. I think rings are better for burgers and sandwiches because they stay in place better. Slices or dices are good on tacos, pizza, or salad.
The onions will last for a week or two in the fridge.
