Lupini beans make fabulous vegan low carb falafels! Here in the UK, pre-prepared Lupini beans are almost impossible to buy so you have to prepare your own using dried beans. This can take anything from 8 to 14 days (I know I know, but it’s worth it!)
I followed this guide here, there is NO mistaking the bitter taste when they’re not ready to use! If you’re in the US then pre-packed lupini beans are readily available (lucky you!).
