Method
- 1
Cook the frozen oven chips according to the pack instructions.
- 2
Melt half the butter in a pan and cook the onions over a low heat for 15-18 minutes, stirring occasionally, until deeply caramelised.
- 3
Mash the black beans roughly, mix with the chopped mushrooms, breadcrumbs and egg, and shape into 4 thin patties. Fry in the remaining butter for 4-5 minutes on each side until golden and firm.
- 4
Build the patty melts: bread, cheddar cheese, a patty, caramelised onion, more cheddar, then a second slice of bread.
- 5
Toast the sandwiches in a dry pan for 2-3 minutes on each side until the bread is golden and the cheese has melted.
- 6
Serve with the chips.
