Rolu(noun) is telugu word for stone mortar and pacchadi is chutney. Roti(telugu pronoun of rolu) pacchadi translates to a chutney made in such stone mortar. This gives a wonderful texture to the chutneys. If one doesn't have such mortar, a mixie can be used. Non-sour greens like palak, kothimir(coriander leaves), gangavaayala koora(purslane) etc are made into chutneys along with few spices. This is something which can be made very easily and the process remains the same for all such sour greens. A little tamarind extract it added to make it more tasty. Green chillies are used in these chutneys. Also, when ripe red chillies(pandu mirapakaya) are available in the season, these replace the regular green chillies. These chutneys go very well with both jonna rottelu and rice. Again, a nice helping of ghee or white butter creates a magic. The image is that of purslane leaves' chutney.
