Now there are hundreds of different recipes for making great burgers, some take more effort than others, some use crackers or breadcrumbs to bulk them out, some even use fillet steak but I like to keep it nice and simple, all in one bowl and then top them with plenty of stuff.
The one in the pic was topped with the rather none to healthy option of smoked bacon, extra chillis, onion rings and cheese but you can top them with as little or as much as you like and serve them with whatever you like. Home made chips are best though (see here for the recipe)
You can also blend the ingredients in a food processor if you dont want to get your hands mucky (or you could wear rubber gloves). I did try to add kidney beans to the mix once but wasn’t keen on the texture so kept it purely to beef for this.
