Aloo bhujia / namkeen

One serving of Aloo bhujia / namkeen — 1 small bowl (30 g) — comes to 174 kcal, 2.2 g protein, 12.7 g carbs and 12.7 g fat. Scaled to 100 g it works out to 580 kcal and 7.3 g protein, which makes it a moderate protein source for a snack item. That single serving is about 11.6% of a 1,500 kcal day and 8.7% of a 2,000 kcal day, so it's more of a filler than a target-hitter on protein without much extra planning.

Walking off Aloo bhujia / namkeen takes roughly 4,350 steps, using the rough approximation of 0.04 kcal burned per step (a population-average estimate for a moderate walking pace, not a personalised number). At ₹8 a serving it costs about ₹72.7 for every 20 g of protein it delivers, which is a mid-to-high price for protein compared with dal, eggs or soya chunks. It fits nearly every Indian diet type, including vegetarian, vegan, eggetarian. It's typically eaten at the evening snack slot. It's a packaged/processed item, worth checking the label against this estimate.

If you want variety without changing the macros much, the closest swaps in the snack category are Bhel puri, Boiled kala chana chaat, Potato chips (packet), Cream biscuit (Bourbon/Hide&Seek type) — each keeps a similar role on the plate while shifting the exact protein-to-carb balance a little.
