prepared kidney beans (equivalent to approx 1.5-2 drained cans), 2 tblsp olive oil, 1 onion, 1 egg, 1/3 tube of tomato paste (or 1 little tin if that is the way it is sold in your country), 125 g bread crumbs, 100 g oats, 2 tsp mixed spices (I happened to have this Smoky Brae rub of mixed spices that included cumin, dried garlic, chilli flakes, and other things, but you may just prefer to add a clove of fresh garlic and some salt & pepper - to your own taste!)
I use dried kidney beans, so I soak them the night before and boil them up the next day. I have started adding a bay leaf to the pot as they are boiling.
and mixed it up thoroughly.
Form into patties, like you would burgers and place on oiled cookie sheets.
Bake at 190C about 15 mins, then flip and bake for another 15 mins. They are a bit dry on their own, but either treat as a burger (with toppings) or eat with sweet chilli sauce, mango chutney or raita (or anything you like) as you would a falafel. Very nutritious and delicious! They freeze just like any meat burger and are great on the bbq.
