Ingredients

• 200 grams Fresh tuna (sashimi-grade)
• 200 grams Cauliflower rice
• 40 grams Cream cheese
• 2 teaspoons Rice vinegar
• 1 teaspoon Erythritol (or keto-friendly sweetener)
• 0.5 teaspoons Salt
• 2 tablespoons Soy sauce (or tamari for gluten-free option)
• 1 teaspoon Wasabi (optional)
• 10 grams Pickled ginger (optional)

Directions

Step 1

Start by preparing the cauliflower rice. In a microwave-safe bowl, microwave the cauliflower rice for 3-4 minutes until soft, removing excess moisture by pressing with a clean kitchen towel if necessary.

Step 2

Mix the cooked cauliflower rice with cream cheese, rice vinegar, erythritol, and salt. Stir thoroughly until the mixture is sticky and holds its shape when pressed together.

Step 3

Divide the cauliflower mixture into 8 equal portions and shape each portion into small oval, rice-like bases, roughly the size of traditional sushi rice pieces. Set them aside on a plate.

Step 4

Using a sharp knife, slice the sashimi-grade tuna into thin rectangular pieces, roughly the size of the cauliflower rice bases.

Step 5

Place one slice of tuna over each cauliflower rice base, gently pressing to adhere. Repeat for all 8 pieces.

Step 6

Optional step: Serve with a small dab of wasabi between the tuna and the cauliflower base for added heat.

Step 7

Arrange the keto tuna nigiri pieces on a serving platter. Garnish with pickled ginger on the side if desired.

Step 8

Serve with soy sauce or tamari for dipping.
