Seitan is a popular meat substitute made from wheat gluten, the protein found in wheat. It has a chewy texture that resembles meat, making it a favorite among vegetarians and vegans. Seitan is often seasoned and cooked in various ways, allowing it to absorb flavors from sauces and spices. Rich in protein, seitan is a versatile ingredient that can be used in stir-fries, sandwiches, and stews. It is low in carbohydrates and fat, but it is important to note that it is not suitable for those with gluten sensitivities or celiac disease due to its high gluten content.
