In a microwave-safe dish, mix the vinegar, water, and salt. Heat in the microwave until the mixture is hot and steaming, 1 - 2 minutes. Or if preferred, bring the mixture to a simmer on the stove in a small pot. Pour the mixture over the onions until the onions are covered, pressing down the onions if needed. If the vinegar doesn't cover the top of the onions just add more water. If there is more room in the jar, feel free to slice up some more onion and add it in.

Allow the jars to cool then store in the refrigerator. The onions will be pickled and ready to eat in 1 hour. They will keep fresh in the fridge for up to 3 weeks.

Tip: once you have eaten all the pickled onions, you can save the leftover brine and either use it in sauces and dressings. Or you can use it to make another batch of pickled onions. Strain out any bits, reheat the liquid in the microwave or in a pot on the stove, and fill the jar again with fresh onion slices.
