A method for making a low or reduced carbohydrate dough for making snack food products with a reduced carbohydrate content. Legumes such as soybeans are cooked near boiling, drained, and milled. Dry ingredients such as starch, fiber, and/or protein can be added to lower the dough moisture content so the dough can be sheeted and cut into pre-forms. The pre-forms can then be cooked, by frying or baking, and seasoned to make a low carbohydrate tortilla-like snack food.
