Creamiest Vegan Alfredo It's the end of the week and I look in the fridge for inspiration in preparing dinner (anyone been here?) I see cauliflower, broccoli, portobello mushroom, and also a block of soft tofu. I know what you're thinking. Stir-fry. However, desiring something richer - I made an Alfredo - and it turned out so delicious, I have to share it with you.
