Hi, I like to keep my burgers simple but tasty. Beat one egg, add two heaped teaspoons of knorr Aromat plus a little salt and pepper , then mix in 500g of extra lean beef mince and using your hands (a bit yucky) until the mince is mushy. Then just make into burgers of the size you want. They do taste really lovely but if you wanted to spice them up a bit just add a few chilli flakes.
