Pizza slice, margherita (Domino's regular)

One serving of Pizza slice, margherita (Domino's regular) — 1 slice (of 7-inch regular, ~70 g) — comes to 189 kcal, 8 g protein, 28 g carbs and 5 g fat. Scaled to 100 g it works out to 270 kcal and 11.4 g protein, which makes it a moderate protein source for a fast food item. That single serving is about 12.6% of a 1,500 kcal day and 9.5% 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 Pizza slice, margherita (Domino's regular) takes roughly 4,725 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 ₹30 a serving it costs about ₹75 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 a vegetarian or eggetarian or non-vegetarian diet. It works at the evening snack slot and dinner. 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 fast food category are Veg frankie (roti wrap), French fries, medium, Ice cream sundae / falooda, McAloo Tikki burger — each keeps a similar role on the plate while shifting the exact protein-to-carb balance a little.
