                                A single slice of vegetable quiche can contain a wide range of protein, from as low as 9 grams to over 24 grams, depending heavily on the specific ingredients and recipe. This significant variation means there is no single answer to how much protein is in vegetable quiche; it is entirely dependent on its composition.
