make the chutney
Add the coriander, mint, red onion, garlic, green chilli, lime juice, cumin powder, chilli powder, black pepper, salt, sugar and water to a blender.
Blend until smooth.
Taste and adjust to your liking - add more lime for tang, chilli for heat or a splash more water to loosen the consistency.
prepare the filling
If your leftover butter chicken contains large pieces of chicken, chop them into smaller bite-sized pieces first.
prepare the samosas
Remove the frozen parathas from the freezer and cut each one in half.
Allow them to defrost slightly until they're flexible but still cool.
Take one half and bring the two straight edges together to form a cone.
Press the overlapping edges together firmly to seal.
fill & seal
Spoon approximately 1 tbsp of leftover butter chicken into the cone, being careful not to overfill.
Press the open edges together, then use a fork to crimp and seal the edge completely.
Repeat with the remaining paratha pieces and filling.
fry the samosas
Heat a generous amount of neutral oil in a deep pan over medium heat.
Carefully add the samosas, working in batches so you don't overcrowd the pan.
Fry for approximately 4–5 minutes, turning occasionally, until golden brown and crispy.
serve & enjoy
Remove the samosas from the oil and drain on a paper towel-lined plate.
Serve hot with plenty of coriander mint chutney for dipping.
