Wrap garlic in cling film lightly and heat in a 600 W microwave for about 1 minute.
Cut the thinly sliced beef offcuts more finely and add the garlic from Step 1. Chop together until the mixture is smooth and season with salt and pepper. Shape into a patty.
Put the patty from Step 2 in a heated pan. Fry both sides over medium heat for 2 to 3 minutes. Place the sliced cheese on top.
Cut the bread horizontally and spread mayonnaise on the cut sides. Sandwich the lettuce, burger, (cheese), onion and tomato.
Story Behind this Recipe
In Sasebo (Nagasaki prefecture), burgers are served for school lunch! The burgers in Sasebo differ from restaurant to restaurant, and so I made my own style of Sasebo burger. You don't have to use burger buns. I used a baguette-type bun this time.
My Hirato beef off-cuts were quite fatty so I didn't use oil to sauté them here. Sasebo burgers are usually served with sweet mayonnaise and BBQ sauce but in this recipe I wanted to enjoy the flavour of the beef by itself so I just used regular mayonnaise and salt.
