High Protein Green Bean Casserole
Nov 21, 2025
This meal is perfect for a Thanksgiving side dish (you can leave out the beans) or eat it as a meal on it's own with the beans! It is the vital wheat gluten that makes this higher in protein, but you can easily sub it out if you prefer. The silken tofu makes it extra creamy, even though it is just a little bit of tofu, it adds a lot to the dish.
