If sweet potatoes have not been prepared ahead of time, prick tops with fork and bake in oven at 400 degrees for approximately 45 minutes. (I use my toaster oven with the convection setting selected. If you are using a traditional oven, the potatoes may require additional baking time.) Set aside to cool when done.
Rinse wild rice mix, drain, and place in a rice cooker.
Add 5 cups of water and cook on brown rice setting.
Transfer cooked rice to a mixing bowl and stir in vinegar, maple syrup and cinnamon until well mixed.
Allow rice mixture to cool while you peel and slice sweet potatoes and avocado into thin strips lengthwise.
Place a nori sheet on a bamboo mat and place about 9 spoonfuls of rice in 3 rows on the nori. (The sticky rice will be easier to spread in small spoonfuls.)
Wet the tips of your fingers (you may wish to have a bowl of cool water nearby for this purpose) and press/spread the rice into a thin layer – working towards the edges of the sheet, leaving about an inch of sheet remaining on the edge farthest from you.
Place a row of sliced sweet potato and inch or so from the edge closest to you.
Top with thin rows of avocado and sliced almonds.
Use a bamboo mat to roll the sushi roll. (Watch a video.) Set sushi roll aside and repeat with remaining ingredients.
Once all ingredients are used, slice the sushi rolls into evenly sized pieces and serve with reduced sodium tamari sauce.
