Homemade pickled red onions

I make these every week, they go great on almost any dish for a pop of acidity.

1 large red onion

1.5 cups vinegar (red wine, apple cider, or white is good)

1 cup water

1 tbsp of sugar

pinch of salt

Cut onions into long strips and place in a glass container. Combine the rest of the ingredients in a pot. Bring to boil to dissolve the sugar, then pour over cut onions! Best after 1-2 days in fridge, good up to 2 weeks :)
