Although some of them tasted more like coffee than others, we found none of the products objectionable. If the idea of soy coffee sounds good to you, you can probably find one that you could drink regularly. There are many soy burgers on the market today, and they vary in taste and mouth-feel. Even true-blue greasy hamburger fans will probably find at least one they deem acceptable. The number two rule with soy burgers is to make sure you are a savvy label reader.
Many veggie burgers contain no soy and are made from vegetables and grains.
Look for soy protein concentrate, textured soy protein or soy protein isolate listed there. Remember, ingredients are listed in order of weight, so choosing a burger with soy protein listed as the first or second ingredient means a higher soy protein content overall. That may be hard to determine without asking the manufacturer. The ones I looked at contain an average of 10 grams soy protein. Be aware, though, that the protein value listed on the Nutrition Facts label refers to total protein, not just soy protein.
