Tips for slicing the red onion
- We like our onion slices in half moons, so I slice the top and bottom off of the onion and toss the outer layer of crunchy skin.
- Then, I slice the onion in half from top to bottom.
- Then, cut side down, I slice each half in ¼ inch pieces.

Variations (pickling other veggies)
You can also use this recipe to "quick pickle" other veggies like cucumbers, okra, peppers, etc. with one small change...
Instead of red wine vinegar, use regular vinegar. Otherwise, the "red" in the red wine vinegar adds a pink-ish color to the veggies.
