Ingredients

• 2 cups Cauliflower rice
• 2 tablespoons Cream cheese
• 1 can (5 ounces) Canned tuna (in water, drained)
• 2 tablespoons Mayonnaise
• 1 teaspoon Soy sauce (or tamari for gluten-free)
• 0.5 teaspoons Salt
• 0.25 teaspoons Pepper
• 2 sheets (cut into strips or small rectangles) Nori seaweed sheets
• 1 tablespoon Sesame seeds (optional)

Directions

Step 1

Place the cauliflower rice in a microwave-safe bowl. Cover and microwave on high for 3 minutes or until tender. Allow it to cool slightly.

Step 2

Once cooled, transfer the cauliflower rice to a clean kitchen towel or cheesecloth. Squeeze out as much excess moisture as possible to ensure the rice stays firm.

Step 3

In a medium mixing bowl, combine the dried cauliflower rice and cream cheese. Mix well until the texture becomes sticky and moldable. Set aside.

Step 4

In a separate small bowl, mix the drained canned tuna with mayonnaise, soy sauce, salt, and pepper. Stir until the tuna filling is creamy and evenly seasoned.

Step 5

With slightly damp hands, take a handful of the cauliflower mixture and flatten it into a small disc in your palm.

Step 6

Add about 1 tablespoon of the tuna mixture into the center of the disc. Carefully shape the cauliflower rice around the filling to form a compact ball or triangle. Repeat with the remaining ingredients.

Step 7

Wrap a small strip of nori around the bottom or side of each onigiri for easy handling. If desired, sprinkle sesame seeds on top for added flavor.

Step 8

Serve immediately or refrigerate for up to 24 hours. Enjoy as a low-carb snack, lunch, or dinner!
