Place the mince, chopped onion, garlic, tomato purée, Worcestershire Sauce, paprika and parsley into a bowl.
*Note* Do NOT add any salt at this point.
Preheat your grill to medium high. Allow to heat for at least 5-10 minutes before cooking the burgers.
While your grill is preheating, divide the meat mixture into 4 equal portions and form into round patties.
Gently press a slight indent into the middle of each burger as this will help to stop your burgers from shrinking
When you are just about to grill, generously sprinkle both sides of the meat patties with salt and pepper.
Then carefully place on the hot grill and cook over medium high with the lid closed for 5 minutes.
Flip the burgers to the other side and continue to grill with the lid closed for an additional 5 minutes for medium/medium rare.
