Add into the bowl the ketchup, peanut butter, bacon bits, liquid smoke, garlic and onion powder and oil. (Everything EXCEPT the nutritional yeast, vital wheat gluten and TVP). Mix together then add the nutritional yeast and TVP and mix again.
Add the vital wheat gluten and mix very well. Once you have mixed the vital wheat gluten into the mixture, start kneading the newly formed mixture for FIVE MINUTES (don’t skimp on this as it changes the texture!). The best technique for kneading is to get a chopping board, smush the mixture like a big pancake, then fold it back on top of each other, repeat and continue kneading for a full 5 minutes.
This is adapted from a recipe on the "Vegan Cooking for Men" blog. The original recipe uses ½ cup BBQ sauce instead of ketchup and calls for the addition of 2 T maple syrup and a bit more oil. However you make it, we think these burgers will become a regular on your grill! http://theveganman.tumblr.com/
