"Soup" as an answer to a bad appetite day falls apart as soon as you ask what is actually in it. A vague broth with whatever vegetables were in the fridge gives volume and very little protein, which is backwards for a body that is already under-eating and still needs an amino acid intake it can hit. This soup is built the other way. Chicken breast and dry lentils are both counted, gram-weighed protein sources, and the potato is the starch that gives the pot body without a roux or a thickener that would blur the numbers.
The batch: 300 g of raw chicken breast, 250 g of gold potatoes, 50 g of dry lentils, and 80 g of mature spinach, simmered in about a litre of water or unsalted stock. That makes two servings, and every figure on this page other than the batch total is quoted per serving. One serving runs 352 kcal, 43.1 g of protein, 36.6 g of carbohydrate, 3.9 g of fat, and 144 mg of sodium. The whole pot, before it is split, totals 704 kcal, 86.2 g of protein, 73.2 g of carbohydrate, 7.9 g of fat, and 289 mg of sodium. Both figures are true at once, and mixing them up either doubles your dinner or halves what you thought you logged.
This is the only meal on this site built to make more than one serving, and that is deliberate. Soup is the format where portioning by eye fails hardest, since a ladle of broth-heavy liquid and a ladle of chicken and lentil solids can look identical and carry very different macros. Batch cooking and weighing the result solves that before it starts.
Ground turkey is the swap when a richer broth matters more than the fat total. Browned before the liquid goes in, 300 g holds protein close to the chicken build while raising the fat noticeably, since ground turkey carries more of it than a trimmed breast, and that extra fat enriches the broth.
The two counted protein ingredients matter more than they look. Chicken alone would put most of the protein behind a single dial. Lentils add a second source that also survives a rough appetite day, because dry lentils dissolve into the broth rather than sitting on a spoon as something that has to be chewed through.
