Soy Textured Protein (TSP) is a concentrated protein product that is generally made from soybeans. It’s a versatile substance that can be used as a meat substitute when seasoning, spices, or herbs are added. It’s especially valuable for people who don’t eat meat, since plant-based foods generally contain less protein than foods from animals. The product can also be used as a meat extender for people who do eat meat.

TVP is sometimes known as textured soy protein or TSP. It’s high in protein and fiber and very low in fat. It’s sold as dried chunks, slices, flakes, granules, or powder and needs to be hydrated before being used. The product has a mild taste on its own but readily absorbs flavor from the liquid in which it’s soaked or cooked. It works well in many foods that traditionally contain ground beef or meat chunks, such as lasagna, chili, veggie burgers, tacos, and “meat” pies.
