How to make spicy tuna roll without mayo?

Question

I really dont like the taste of mayo in my spicy tuna roll and most of the recipes seem to have a decent amount of mayo, like 4 parts to 1 part spice. I'm looking for a recipe to make the rolls that a lot of restaurants use, its a bright red spicy tuna mixture and there is no mayo flavor. Maybe they use mayo but it is a smaller amount than some of the other recipes call for. If you know which recipe Im talking about can you also please be very specific on which spices to use? Like the brand and name? I've bought some hot chili sauce but it tastes sweet.

Thanks Much! and Happy Sashami!

I found this receipe online and tried it today. I think I found the right spices for the flavor I was looking for:

INGREDIENTS
•half sheet of Nori seaweed
•fresh tuna - sliced
•1 1/2 tsp Sichimi Togarashi ("7 flavors chillies")
•sesame chillie oil
•prepared sushi rice
•wasabi
•soy sauce for dipping
•pickled ginger, for garnish
To prevent rice from sticking to mat, wrap mat in clear wrapping paper.

To prepare:
•Cut tuna into 1 inch thick slices
•Rub tuna with about 1 1/2 tsp of the Sichimi Togarashi and allow to marinate
•Coat very lightly with oil only after marinating with the spice first, otherwise the oil will act as a barrier, preventing the spice from seasoning the tuna
•For a slightly milder roll, use sesame oil instead of the sesame chillie oil
•Place the half sheet of nori on the rolling mat
•Spread a thin layer of rice onto the sheet, leaving a small space uncovered at the ends
•Layer tuna in the center of roll
•Holding the filling in place,

Answer 1

why not change it up and go with a wasabi paste mixed with a little bit of mayo (like 3 parts wasabi and 1 part mayo) call your favorite sushi place and ask them to tell you how to make it.
