A home-made burger with three of my favourite French elements included in the ingredients, Bearnaise sauce, French blue cheese and sliced red onions! I made these for a quick lunch on Bastille Day - 14th July, hence the name! I used our excellent local Charolaise beef, a salt marsh beef which is superb, with a good fat to muscle ratio, and a slight tang of herbs and salt. If you want to cut down on the carbs, just have this burger "Naked" without the bun! Likewise for low fat - omit the Bearnaise sauce and chop some fresh tarragon up and mix it with the minced/ground beef. I am not a great lover of commercial burgers, but I do like home-made burgers - and these are now a firm favourite with all my family & friends! This recipe is for 2 people - just increase the ingredients for more people.
