The cauliflower rice was half a cauliflower, pulsed in the food processor, plus one carrot, likewise, plus sesame seeds, salt and liquid from the can of inari wrappers. The dolmades were from a can, and were a sort of jokey last minute addition to fill out this meal.
I read that there are various options with inarizushi: you can use plain rice, sushi rice or sweet rice (okay, cauliflower) like I did here. I think I might prefer sushi seasoning over the sweet version.
Also, it should be noted that Inari herself, as the goddess of rice, would be very unhappy with these cauliflower imposters. I'm not sure how foxes would feel about them.
