Ingredients

• 200 grams Cauliflower rice
• 1 tablespoon Rice vinegar
• 1 teaspoon Granular erythritol (or your preferred low-carb sweetener)
• 0.25 teaspoon Salt
• 200 grams Fresh tuna (sushi-grade, thinly sliced)
• 2 tablespoons Soy sauce (optional, for dipping)
• 2 tablespoons Pickled ginger (optional, for serving)
• 1 teaspoon Wasabi (optional, for serving)

Directions

Step 1

Prepare the cauliflower rice by steaming or microwaving it until tender (about 3-5 minutes). Allow it to cool to room temperature.

Step 2

In a small bowl, mix the rice vinegar, granular erythritol, and salt until the sweetener and salt have dissolved.

Step 3

Transfer the cooked cauliflower rice to a larger mixing bowl and pour the vinegar mixture over it. Mix thoroughly to evenly coat the cauliflower rice.

Step 4

Take a small amount of the cauliflower rice (about 1 tablespoon) and shape it into an oval or rectangular mound using your hands. Repeat this step until all of the cauliflower rice is shaped into mounds.

Step 5

Lay a slice of fresh sushi-grade tuna over each cauliflower rice mound, gently pressing it down to secure it in place.

Step 6

Arrange the low-carb tuna nigiri on a serving plate. Serve with soy sauce, pickled ginger, and wasabi on the side if desired.

Step 7

Enjoy your low-carb tuna nigiri immediately for the best texture and flavor.
