Vegetarian Passover

Over the years I have struggled with how to keep Passover as both a vegan and an Ashkenazi Jew. Most of my protein sources, such as beans, lentils, and tofu, are off limits during Passover (but quinoa seems to be ok!). To make matters worse, when I first went vegan Passover usually overlapped with my final exams, which made it that much more difficult. Rather than risking feeling weak and tired while studying, I opted to follow the Sephardic tradition during Passover, which meant the protein-based kitniot was back on the table (literally). I have found that this is the right balance for me. How do you keep Passover as a vegetarian or vegan?
