Masoor dal (red lentil)

One serving of Masoor dal (red lentil) — 1 katori (30 g raw dal) — comes to 130 kcal, 7.3 g protein, 15.8 g carbs and 4.2 g fat. Scaled to 100 g it works out to 87 kcal and 4.9 g protein, which makes it not a meaningful protein source on its own for a dal & legume item. That single serving is about 8.7% of a 1,500 kcal day and 6.5% 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 Masoor dal (red lentil) takes roughly 3,250 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 ₹6 a serving it costs about ₹16.4 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 works at lunch and dinner. It's a daily staple in most Indian kitchens and one of the cheaper ways to hit a protein target.

If you want variety without changing the macros much, the closest swaps in the dal & legume category are Besan chilla, Chana sundal (South Indian chickpea stir-fry), Chole / chana masala, Chana dal — each keeps a similar role on the plate while shifting the exact protein-to-carb balance a little.
