I was recently introduced to the concept of baked sushi, basically a baked version of in which you layer the rice, furikake, and sushi fillings in a casserole dish then bake it altogether. To serve, you spoon the layers into a piece of nori and enjoy. I figured this could be something that I could do with cauliflower rice instead.

The trick was finding a way to get the rice to have that sushi vinegar taste and still be able to stick together when baked. Cooking it up with cream cheese works great because it absorbs the rice vinegar while also making the cauliflower sticky enough to hold the other ingredients together. It works fine with regular cream cheese, but I actually prefer using my vegan tofu cream cheese instead to make it a little less rich and the flavour works well too.
