spray a pan with rice bran oil, then soften the onion for a couple of minutes
add the spices and cook for a further minute
add the red kidney beans, tomatoes and tomato paste then simmer for approximately 10 minutes adding a little water if needed - the mixture needs to be wet but not runny.
Mash the bean mixture and place in a serving bowl
Whilst the beans are simmering, in a bowl, mash the avocado then add the chopped tomato, lemon juiice (approx 1 x tblspn), tabasco sauce,salt and pepper and mix.
Place the pita bread rounds into the oven at 180C for approx 5 minutes or until slightly browned. Once these are removed from the oven they will crisp up and can be broken into pieces as required.
