Soy Food
Description
Green soybeans Fresh soybeans can be eaten as snack or meal after boiling them in lightly salted water for 15-20 minutes.
Hydrolyzed vegetable protein Hydrolyzed vegetable protein is made from soybeans and other vegetables. It can be added to soups or casseroles to add protein and flavor.
Miso Miso is a paste made from soybeans, grain, and salt. Miso can be used to make soup or sauces.
Soy cheese Soy cheese is made from soy milk and can be used as a substitute for sour cream, cream cheese, or cheese.
Soy flour Soy flour is made from ground roasted soybeans. Soy flour can be added to baked goods to add protein. However, soy flour cannot be used in place of all of the flour in a recipe because it doesn't have gluten, which is a protein needed to help dough rise.
 
Soybeans Whole soybeans can be soaked and added to stews and soups for flavor and protein. They can also be roasted for snacks.
Soymilk Soymilk is made from soybeans that have been soaked in water, ground, and strained. Fortified soy milk (which has added calcium and vitamin D) can be used instead of milk as a drink, in cereals, and in other recipes. Soy milk comes plain and in different flavors such as chocolate and vanilla.
Soy nut butter Soy nut butter is made from roasted whole soy nuts, which are crushed and blended with soy oil. The butter can be used in place of peanut butter and is a great substitute for people who are allergic to nuts.
Soy nuts Soy nuts are made from soybeans, which are soaked and then baked. They can be eaten as a snack, added to trail mix, or used as a salad topping.
Tempeh Tempeh is made fermented soybeans and grain. Tempeh can be marinated and grilled and added to soups, casseroles, or chili.
Textured soy protein, textured vegetable protein (TSP/TVP) Textured soy protein/textured vegetable protein is made from soy flour. It's most often used with, or instead of, meat in casseroles. If TSP/TVP is substituted for meat, other flavorings then need to be added. TSP/TVP can be bought as dried kernels and then prepared with boiling water.
Tofu Tofu is made by curdling fresh, hot soy milk. Firm tofu can be used in soups, stir-fries, and casseroles. Silken tofu can be used for dips and dressings. Tofu is popular in many lunch or dinner entrees.
