Can you cook pickled onions? Can you cook hot dishes with pickled onions?  I've never seen a recipe which uses them hot, is this just because they don't taste good hot?  What hot dishes might be appropriate to put pickled onions in?
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.
