In a large pot, combine the polenta, garlic powder, sesame oil, water and mushroom broth (or other broth) over medium heat. Once boiling, bring down to a simmer, and gradually add the almond milk (1/4 cup at a time every 5 minutes or so). Stir occasionally to keep the bottom from burning.
After about 20-25 minutes of simmering, start to caramelize the onions.
In a shallow pan or pot, combine the onion, garlic, and olive oil, and cook over medium heat until fragrant and the onions are starting to be translucent.
Add the mushrooms and mushroom broth granules (or the salt, balsamic vinegar and sugar) and cook over medium low heat until the mushrooms have caramelized and onions have cooked down. This may take about 10 minutes with occasional stirring.
Continue to cook and stir the polenta until it starts to thicken and when you give it a taste, it is no longer gritty. By now, you should have incorporated all of the almond milk and the polenta should be fairly thick. It should have the texture of thick oatmeal, and will start to pull away from the sides of the pot.
To serve, place the mushrooms on a bed of polenta and garnish with veggie chips (TERRA Stix) for added texture.
