The chicken in this build is plated, cooked weight, not raw. Weigh the roasted breast after it comes off the tray and log it against a cooked chicken breast record, the way you would for the wrap. There is no raw-to-cooked conversion running on this page, so do not weigh raw chicken here and do not apply a yield factor to it. If your chicken was a rotisserie bird or a batch you roasted two days ago, plated weight is the only number you have anyway, and it is the correct one to log.
The dressing is where this bowl actually gets tracked wrong, and the fix is to measure it before it hits the bowl rather than after. A level tablespoon of olive oil is 13.5 g, which prices out at 119 kcal on its own, close to a quarter of the entire undressed salad in one spoonful. A pour straight from the bottle runs closer to three tablespoons, about 40.5 g, which is 358 kcal, nearly as much as the rest of the bowl combined. Build the dressing on lemon, vinegar, mustard, and yogurt first, and treat the oil as the last, deliberate addition rather than the default. A spoon that measures the oil onto the salad, instead of a bottle tipped over it, is the entire difference between the 496 kcal version and something closer to 850.
Fiber and sugar read as unavailable for this bowl, and that's not the same as zero. The chickpeas report 4.7 g of fiber and the chicken and egg both report a measured 0 g, but the romaine and the avocado carry no fiber value at all, so the total can't be summed and stays withheld rather than presented as complete. Sugar is unavailable for the same reason: only the egg's 0.1 g and the chicken's 0 g are measured, and the romaine, chickpeas, and avocado all lack a reported figure.
A restaurant version of this salad is the specific case where you can't weigh anything. The chicken arrives already sliced, the dressing arrives already on the bowl or in a ramekin you can't measure, and the greens are whatever volume the kitchen decided on. Log this page's undressed baseline, 496 kcal and 50.9 g of protein, as a floor, and round the fat and calorie total upward on purpose rather than trusting the menu description. Ordering the dressing on the side doesn't make it measured. It just moves the same unmeasured pour from the bowl to a small cup next to it.
