To a deep/ large non-stick pan, add half of the oil and fry the halloumi on a medium heat until golden and crispy, for approx 2 minutes on each side. Set the halloumi aside.
Add the remaining oil into the pan along with the onion. Gently fry, seasoning with a pinch of salt, for around 4 minutes, or until softened.
Next, add the garlic, spices (curry powder, garam masala and turmeric) into the pan along with the ginger. Fry for two minutes to bloom the spices.
Pour the passata into the pan, as well as the stock. Cook for 10 minutes uncovered on a medium/low heat.
After this time, add the cavolo nero and half of the halloumi into the pan. Stir to combine and pop the lid on. Cook for a further 5 minutes.
Reduce the heat and stir the cream and lime juice into the pan. Taste to see if any salt is needed. Serve with a portion of rice, some crispy reserved halloumi and fresh mint to top. If you love a bit of heat add chilli flakes or red pepper flakes. Enjoy!
