In a large bowl whisk together the vegetable broth, tomato paste, and white miso pasted until smooth. Now add the sun-dried tomatoes, nutritional yeast, dried basil, brown sugar, fennel seeds, dried rosemary, salt, crushed red pepper flakes, liquid smoke, and all of the sautéd onions and garlic along with any oil leftover in the pan, and stir to combine. Lastly, add the vital wheat gluten and combine to make a dough. Knead the dough to make sure it’s all combined, but once combined, stop kneading. The more you knead the tougher the sausages will get so only do as much as is needed to incorporate the vital wheat gluten.
