Combine 1 cup hot water with 1/2 cup apple cider vinegar, 1 Tablespoon of sugar and 1 teaspoon of salt.
Slice your red onions or your cucumbers (or both, assuming you keep them separate)
Add your sliced veggies into a 1-quart mason jar. (Again, I prefer to keep my cucumbers separate from my onions)
Pout the water/vinegar mixture into each jar and tighten with a lid.
Veggies are “pickled” after only one hour, and can be refrigerated for up to two weeks.
Put these on everything! Sandwiches, tacos, salads, etc. their tang and crunch can’t be beat!
