This recipe is Low FODMAP - it contains no onions, garlic or beans. I always used to use a lot of onion in a dish like this but it is surprising how you don't notice that it is missing. A FODMAP-friendly tip is to use garlic infused oil to add some garlic flavour. The FODMAPS in garlic are soluble in water but not in oil, so you can use the infused oil without having to worry.
Depending on how sensitive my stomach is feeling, I sometimes leave out the chilli powder. This may not make it authentic, but I find that the paprika and other spices still give it a nice flavour.
I normally serve this with rice, but it's also nice as a jacket potato filling.
