1lb/500g ground beef
1 half onion grated or finely chopped
4 pinches ground coriander
4 pinches paprika powder
a little pepper, fresh ground is better
a little salt
1 hand fresh bread crumbs
1 egg lightly beaten
1 quarter beef stock block dissolved in a quarter cup water

For the Rolls:
4 rolls
sliced tomato
thinly sliced onion
lettuce
a few slices of gherkin
mayonnaise
ketchup

Methods:

Mix all the patty ingredients thoroughly,leaving the salt for after the patties are cooked if you prefer.
Make sure the mixture is cool.Divide mixture into 4 equal balls and mold into patties.

Cook on medium heat under the grill, on the barbecue or in a pan until the patty is cooked to your preferred degree of doneness or the internal temp reaches 160F/70C.

Split the rolls and toast the cut surfaces lightly (under grill, on barbecue or in a pan) just before the patties are done. Spread mayonnaise on the bottom halves, add a thin slice of onion, some lettuce, a slice of tomato and a little sliced gherkin. Top it off with a little mayo and ketchup, the patty and the top half of the roll.
