I'm not sure bean burgers would make for less whiffy nappies, but if you want to have a go, there a couple of recipes here:-
Big Beany Burgers (makes 2 toddler portions)
2 teaspoons oil
1 small onion
1 small garlic clove, crushed
I teaspoon ground cumin
1 teaspoon ground coriander
10oz can kidney beans, drained and rinsed
A little flour
Heat half of the oil in a pan and gently fry the onion and garlic until lightly browned. Add the spices and cook for 1 minute.
Drain and rinse the beans, add to the onion mixture, and mash (or blitz briefly in a food processor). Divide the mixture in half, shape each half into a burger shape using floured hands.
Fry the burgers in the remaining oil for 3 - 4 mins each side, or until browned.
Bean and Feta Falafel (4 toddler portions)
10 oz broad beans
One onion, chopped
teaspoon ground cumin
a teaspoon ground coriander
4oz feta cheese, drained and chopped
1 tablespoon sunflower oil
Boil the broad beans for a few minutes, drain, then add to a food processor with the onion, spices and feta (or mash the ingredients in a bowl).
Divide the mixture into 12 portions, then press into oval patties between floured hands. Heat the oil in a frying pan and fry for 5 minutes until each side is golden.
