Use the internet or recipe books that you can find in the library to look up recipes for traditional Punjabi foods.

You can then make a recipe book of foods that you might find in many langars.

You may also like to cook these foods and bring them in for the class to share.

Or, have each person in the class cook a different food from their culture and bring it in for a class langar. Make sure you observe the rules of the langar: only vegetarian food, everyone sits in rows on the floor, and no fighting over who sits where.
