A handful of groundnuts provides some protein. Weigh your usual handful once so you can turn the number on the pack into an estimate for your snack.
Do the small bit of maths
The Indian Food Composition Tables list 23.65 g of protein per 100 g for raw groundnuts. A 25 g helping works out to about 5.9 g. If you eat roasted or coated groundnuts, use the figure on that pack for your estimate. ICMR-NIN, Table 1, entry H012 Use the nutrition row for the actual groundnuts you eat, especially if they are coated or mixed with something else.
Make it a snack you will pack
Put the handful in a small dabba with a separate fruit. If you share snacks at work, check whether anyone has a peanut allergy before putting it out. See the office snack ideas · Indian Food Composition Tables

Compare the snacks you already like
Weigh one handful of plain groundnuts and one usual helping of your other snack. Look up each product on the same weight basis before converting to your own portion. If one mix contains sev or a coating, use the label for that mix. A comparison between two actual dabbas is easier to use on a workday than a list based on 100 g of every snack.
