Can you cook pickled onions?
This afternoon, I made a veggie/bean chilli. When preparing, I was surprised to notice that we are out of fresh onions. I decided to use a can of pickled onions in the chilli. 

60 minutes later and this is my happy finding...that the pickled onions have retained crunch and infused the chilli sauce with the most gorgeous deep and rich sweetness. Pickled onion chilli can rest and infuse a wee bit more.
