Pickled red onions are easy to make with onions, lime juice, jalapenos, radishes, and vinegar and the perfect topping for tacos, salads, and sandwiches.
Slice the onions with a mandoline with the middle thickness. Slice the radishes with the thinnest setting and the jalapenos with the thickest setting or a knife.
Layer the onions, radishes and peppers into the jars.
Top with salt, honey, and peppercorns.
Squeeze juice from two limes into each jar and then pour vinegar until jar is 1/2 full.
