Spray a non-stick frying pan with a little 1-cal cooking spray. Add the onion and spring onions, season with salt and pepper and fry over a low heat for about 5 minutes, until softened but not coloured
Add the garlic, chilli and Cajun spice, then fry for 2–3 minutes. Tip into a bowl, add the beans and roughly mash
Leave to cool slightly, then add the egg, breadcrumbs, coriander and lime juice. Season well, then mix to combine. Gently stir in the crumbled feta
Wet your hands lightly, then shape the mixture into 4 large patties. Chill in the fridge for 20 minutes to firm up
Preheat the grill to medium. Spray a little more cooking spray in a grillproof frying pan and heat over a medium heat. Add the burgers and fry for 3–4 minutes on each side, until golden brown. Top each burger with a slice of halloumi, then cook under the grill for 3–4 minutes, until the cheese is bubbling and melted
Serve in toasted buns topped with guacamole, rocket leaves and sliced tomatoes, if desired
How to freeze:
Place the uncooked burgers on a baking sheet lined with non-stick baking paper
Freeze until they are solid, then pack into a freezer-proof plastic container and freeze for up to 3 months
You can cook the burgers from frozen; preheat the oven to 200˚C/400˚F/Gas mark 6 and preheat a baking sheet. Place the burgers on the hot baking sheet and spray with 1-cal cooking spray on both sides
Cover loosely with foil and bake for 30 minutes, turning halfway through
Preheat the grill to medium. Remove the foil, cover each burger with a slice of cheese and grill for 3–4 minutes, until the cheese is melted and bubbling
