Ingredients You’ll Need
Here’s everything you need to make Spicy Tuna Bowls with Cauliflower Rice:
- For the tuna:
- 2 cans of tuna in water (or fresh seared tuna, if you prefer)
- 2 tablespoons sriracha (adjust to taste)
- 2 tablespoons low-sodium soy sauce or coconut aminos
- 1 tablespoon sesame oil
- 1 teaspoon rice vinegar
- 1 teaspoon honey (optional, for balance)
- 1 tablespoon mayonnaise or Greek yogurt (for creaminess)
- 1 clove garlic, minced
- 1 teaspoon grated fresh ginger
- For the cauliflower rice:
- 1 medium head of cauliflower (or 3 cups pre-riced cauliflower)
- 1 tablespoon olive oil
- Salt and pepper, to taste
- For toppings & add-ins:
- 1 cup shredded carrots
- 1 cucumber, thinly sliced
- 1 avocado, diced
- 2 green onions, chopped
- Sesame seeds for garnish
- Optional: sliced jalapeños, shredded cabbage, or edamame
Step-by-Step Instructions
Step 1: Prep the cauliflower rice
If you’re using fresh cauliflower, cut it into florets and pulse in a food processor until it looks like rice. Heat olive oil in a skillet over medium heat, add cauliflower rice, and sauté for about 5–7 minutes until tender but not mushy. Season lightly with salt and pepper.
Step 2: Make the spicy tuna mix
In a medium bowl, combine tuna, sriracha, soy sauce, sesame oil, vinegar, honey, mayonnaise/Greek yogurt, garlic, and ginger. Mix until everything is well coated. Taste and adjust spice level if needed.
Step 3: Assemble the bowls
Divide the cauliflower rice evenly into 4 meal prep containers. Top each with equal portions of spicy tuna. Add fresh veggies (cucumber, carrots, avocado, etc.) around the tuna. Garnish with sesame seeds and green onions.
Step 4: Store or serve
Enjoy immediately or cover and refrigerate for up to 4 days. For meal prep, leave avocado out until the day you eat for best freshness.
Meal Prep Tips
- Keep veggies fresh: Store toppings like avocado separately and add right before serving.
- Make it spicier: Add extra sriracha or chili flakes.
- Add more protein: Toss in edamame or a boiled egg on the side.
- Double the recipe: This makes about 4 servings, but it’s easy to scale up.
- Storage: Best eaten cold or at room temp; no need to reheat!

Why Cauliflower Rice Works So Well
Switching to cauliflower rice isn’t just about cutting carbs—it’s also about adding more vegetables to your meals. Cauliflower is rich in vitamin C, folate, and fiber, all of which support digestion and overall health. Plus, it soaks up flavor beautifully, meaning it pairs perfectly with the bold, spicy tuna mix.
Budget-Friendly Eating That Feels Gourmet
One of my goals with recipes like this is to show that eating healthy doesn’t have to break the bank. Canned tuna is one of the most affordable protein sources out there, and when paired with inexpensive veggies and cauliflower rice, this meal costs just a fraction of what you’d spend on sushi takeout or a poke bowl.
Variations to Try
- Vegetarian version: Swap tuna for chickpeas or tofu and use the same spicy sauce.
- Rice option: Use brown rice or quinoa if you want more complex carbs.
- Extra crunch: Add shredded cabbage, edamame, or even roasted chickpeas.
- Low-sodium version: Use coconut aminos instead of soy sauce and skip added salt.
FAQs
Q: Can I use fresh tuna instead of canned?
A: Absolutely! Sear fresh tuna steak, chop it into small pieces, and mix with the sauce. It’s delicious but more expensive.
Q: How long does this last in the fridge?
A: Up to 4 days if stored in airtight containers. For best taste, add avocado the day you eat it.
Q: Can I freeze it?
A: I don’t recommend freezing since the tuna and veggies lose texture. Stick to fridge storage.
