I add usually what I have also by adding garlic it gives it that extra taste but it's a recipe open for what you like to add that works for you. Variety of different ways using what ever you have.Something similar is a standard in our house. "Fridge Cleaner" as my son calls it. Basically what ever veggies are on hand but because my family like it spicy we add Garlic, Ginger and minced chilli or a little sweet chilli sauce instead. I normally make a large batch so there are leftover for anyone and it packs easily for lunch at work. so many simple variations to suit every palate and budget. Have also tried with Tuna instead of bacon - was requested to not do that again please!
