My wonderful and darling friend Molly whom I miss ferociously, taught me to do this to red onions.
Slice red onions thinly ( I use a mandoline)
Squeeze lots of fresh lime juice on them
Keep refrigerated for a few hours
It’s kind of like onion ceviche and they turn limp and DELICIOUS and make a dazzling accompaniment to tacos of all kinds and sandwiches and anything else that needs a sassy kick in this warm weather. Do it.
Sidenote: They look like tentacles, don’t they?
