Fried breaded fish tacos with spicy peppers, fresh coriander, lime and Mexican style pickled red onions / on Old El Paso gluten free taco shells

Quick & Easy Pickled Onions i.e. the Best Garnish

Today I thought I’d share a very simple pickled onions recipe I’ve been loving and made so many times recently. It’s incredibly quick and easy to make and such a great garnish that adds a boost of flavour to just about any dish.

…. But it’s especially amazing in tacos and burrito bowls. πŸ˜›

1. Feel free to use any vinegar you’d like, but red wine is by far my favourite.

2. Toasting the cumin seeds and ancho chilli flakes isn’t absolutely necessary (if you can’t be bothered), but it does add to the flavour. πŸ˜‰

3. Feel free to play around with the flavours. In reality you can add whatever seasonings you’d like.
