To make the sauce: Heat the olive oil in a frying pan. Add the onion, garlic and paprika and sauté for 2 minutes. Add all of the remaining sauce ingredients and bring to boil, stirring regularly.
Reduce the heat and allow to simmer with the lid on for 30 minutes, stirring occasionally. Remove the lid and simmer for an additional 10 minutes. Check the seasoning then remove from the heat and set aside to cool.
Make the beef patties by combining the beef mince, onion, mustard, Worcestershire sauce, salt and pepper in a bowl. Mix together well – I find it easiest to use my hands.
Divide the mixture in half, then shape each half into a patty.Heat some olive oil in a griddle pan. Fry the hamburger patties for 5-6 minutes per side or until cooked through.Place a few lettuce leaves on each toasted hamburger bun. Top with the cooked patty, some gherkins, the tomato, cheese and a few spoonfuls of monkey gland sauce.
