In a large mixing bowl, mix up the 3 cans of crab meat, ½ cup of crushed butter-flavoured crackers, finely chopped onion slices and ½ cup of the sliced green pepper. Cover this mixture and place aside.
Take a small bowl and blend the ¼ cup of mayonnaise, 1 large lightly beaten egg, and 1 teaspoon of salt, 1 teaspoon of ground mustard and 1 teaspoon of Worcestershire sauce in it.
Dust the mayonnaise mixture with ¼ teaspoon of garlic powder and drizzle half teaspoon of lemon juice over the top. Use a large spoon to unify this mixture well.
Now add it into the previously mixed up mixture in the large bowl and bring together both ingredients until uniform and forms a smooth mixture.
Cover the bowl and place in refrigerator for few minutes to thicken and stiff.
Once chill well, remove the bowl from refrigerator, unseal and place on your work surface. Now add some flour to your hands and shape the crab meat-mixture into 6 equal patties. Coat them with some flour – of you like.
Pour ¼ cup of canola oil into a large non-sticking frying pan or skillet and set it on stove’s medium heat range to warm well.
Now place the crab meat patties in the skillet or frying pan’s oil and fry them for about five minutes on each side or until nicely browned from all sides.
Use a large skimmer to take out the fried crab meat patties from the oil and place on a kitchen towel. Now let the towel to absorb the oil for some time.
In the mean time, cut the 6 bread buns or hard rolls into halves and arrange with some fresh lettuce leaves, tomato slices and onion slices – if you like.
Now set the warm crab meat patties on the top of the garnished bun slices and top with the other halves.
