Step 1: Prepare the Cauliflower Rice - Start by chopping the cauliflower into florets. Use a food processor to pulse the florets until they resemble rice grains. This should yield about 4 cups of cauliflower rice.
Step 2: Cook the Cauliflower - Transfer the cauliflower rice to a steamer or microwave-safe bowl. Steam it for about 5-7 minutes or until tender. Once cooked, let it cool slightly.
Step 3: Season the Cauliflower Rice - In a mixing bowl, combine the cooked cauliflower rice with salt, white vinegar, and sugar-free powdered sugar. Mix well until all the ingredients are evenly distributed.
Step 4: Prepare the Nori - Lay a sheet of nori on a bamboo rolling mat, shiny side down. Make sure it’s placed horizontally in front of you.
Step 5: Spread the Cauliflower Rice - With wet hands (to prevent sticking), take a handful of the cauliflower rice mixture and spread it evenly over the nori, leaving about an inch of space at the top.
Step 6: Add Fillings - In the center of the rice, place a line of the mayonnaise, followed by your choice of sushi-grade salmon (or other protein) and cucumber strips.
Step 7: Roll the Sushi - Starting from the bottom, use the bamboo mat to gently roll the sushi away from you, applying slight pressure to ensure it holds together. Roll it tightly, stopping when you reach the open edge of the nori.
Step 8: Seal the Roll - Use a little water to moisten the edge of the nori, then press it down to seal the roll.
Step 9: Slice and Serve - With a sharp knife, slice the roll into bite-sized pieces. Sprinkle with sesame seeds for garnish. Serve with wasabi on the side for an extra kick!
