Best Sushi / sushi burrito for celiac? (avoids cross-contamination)

Idk if I'll get any answers but wanted to post - Just as the title says, I am celiac and very sensitive to the different oils that are added to raw fish. My husband is a big sushi fan and I want to try something that has fresh salmon with minimal added ingredients. Big points if they have cooked fish as an option too. Appreciate it!
