Mrs Shikra, i used Shinoo’s naan ki recipe to make the naans. For the keema part, i bhoonafied the keema like you do for salans but added very little tomatoes. you dont want it to be runny but rather dry. Now take a paera of the dough, roll it out a bit, put some keema in between and bring the edges together like you are makng a paera again but now with keema in the middle. Now roll it out again and proceed as usual, like Shinoo has listed.
Here is the recipe for the naan:
