In a food processor chop finely the onion, garlic, and celery.
Seperatly chop nuts and set aside.
Heat oil and add the onion, garlic, and celery--saute until soft.
Add the nuts and bulgur wheat and saute for a couple of minutes
until golden brown. Add the stock and simmer until the liquid is
absorbed.
Stir in tomato puree, parsley, herbs, and the egg. Season with salt
and pepper and leave until cool enough to handle.
Shape into patties and either cook in oven at 400°F/200°C/Gas 6 for
15 to 20 minutes until heated through or cook in frying pan. Place
in burger buns with your favorite garnishes. I like cooked onion
rings, lettuce, cheese, and fresh tomato.
If you have problems with the burgers falling apart when cooking
try adding some grated cheese before shaping, this helps.
An alternate serving suggestion is like a falafel. Take tablespoon
sized amounts of mixture and fry in some oil until gold to dark
brown. Put inside lightly warmed Pita bread with some salad and
Chilli sauce.
You can substitute your favorite nuts for the Brazils.
