Crispy Beef Burger Toasties with Green Goodness Filling

These are basically somewhere between a smash burger, lahmacun and a toastie, beef mince pressed directly onto the inside of the bread, pan-fried until deeply golden, topped with melted cheddar, then filled with creamy avocado and rocket tossed through a garlicky herby kefir dressing. They’re quick, satisfying and properly CBF-friendly.
