ByCharlotte Montgomery October 17, 2025October 17, 2025

Introduction

Spicy Tuna Bowls with Cauliflower Rice are a flavorful and healthy meal prep option. Combining tender cauliflower rice with zesty, creamy tuna and fresh cucumber, these bowls are perfect for quick lunches or light dinners.

The dish is served in a round white bowl with three layers. The bottom layer is white rice mixed with black and white sesame seeds, creating a speckled texture. The middle layer is a creamy, light orange mixture placed in the center of the rice, with a slightly chunky texture. On top of this creamy layer, there are small pieces of chopped green onions scattered evenly. Along one side of the bowl, there is a row of thin, round cucumber slices sprinkled with black and white sesame seeds. A pair of light brown wooden chopsticks rest on the edge of the bowl, angled across it. The bowl sits on a white marbled surface. photo taken with an iphone --ar 4:5 --v 7

Ingredients

3 cups cauliflower rice
1 tbsp seasoned rice vinegar
3 (5 oz) cans of tuna, drained
1 Persian cucumber, thinly sliced
1/2 tbsp toasted black sesame seeds
1/2 tbsp toasted white sesame seeds
2 green scallions, thinly sliced
3/4 cup mayonnaise
1 1/2 tbsp sriracha sauce
1 tsp toasted sesame oil

Instructions

Step 1: Steam the cauliflower rice until tender. While it’s still hot, drizzle with the seasoned rice vinegar and mix well. Taste and add more vinegar if desired. Divide 1 cup of cauliflower rice into each meal prep container.
Step 2: In a large bowl, combine the mayonnaise, sriracha sauce, and toasted sesame oil to make the spicy mayonnaise. Adjust sriracha to your preferred spice level. Add the drained tuna to the bowl and gently mix until the tuna is evenly coated.
Step 3: Evenly divide the spicy tuna among the meal prep containers. Add the thinly sliced cucumbers to each container. Sprinkle black and white sesame seeds over the rice and cucumbers, then garnish the tuna with sliced scallions.
Step 4: Store the containers in the fridge for up to 3 days. Enjoy chilled or at room temperature.

Tips & Variations

For extra crunch, add shredded carrots or diced avocado to the bowls.
Use light mayonnaise or Greek yogurt for a lighter sauce.
Replace sriracha with chili garlic sauce for a different spicy twist.
Toast your own sesame seeds lightly at home for fresher flavor.

Storage

Store the prepared bowls in airtight containers in the refrigerator for up to 3 days. They are best served cold or at room temperature. Avoid freezing, as the texture of the cauliflower rice and tuna mixture may change.
