Rapini is not the same as Sarson ka Saag. Sarson ka Saag is a traditional Punjabi dish made with mustard greens, while rapini is a leafy green vegetable that is commonly used in Italian and Mediterranean cooking. However, in Canada, rapini is often used as a substitute for mustard greens to make Saag due to its similar taste and texture. So, while rapini may not be the traditional ingredient used in Sarson ka Saag, it can still be used to make a delicious and healthy Saag in Canada.
