Like many people, I used to think tuna only belonged between two slices of bread. That’s how my mom packed my school lunches, and I never questioned it. But one day in college, when my budget was tight and my pantry was nearly empty, I mixed a can of tuna with some leftover rice. What started as a desperate meal turned into my go-to lunch. It’s simple, filling, and costs less than ordering takeout. Now I keep cans of tuna in my pantry just for this dish.

Ingredient Substitutions
Canned tuna can be replaced with canned salmon or chickpeas for different protein options. Salmon provides similar omega-3 fatty acids, while chickpeas offer a plant-based alternative rich in fiber. Adjust seasoning as needed, as these substitutions may have milder flavors than tuna. Japanese mayonnaise can be swapped with Greek yogurt or avocado for a healthier twist. Use slightly less Greek yogurt due to its tangier taste, or mash half an avocado for a creamy texture. Steamed rice can be substituted with cauliflower rice or quinoa for lower-carb or higher-protein options. Cauliflower rice may require less cooking time, while quinoa should be prepared according to package instructions. These alternatives provide different textures and nutritional profiles while maintaining the bowl’s overall structure.

Ingredients
For the tuna salad:
- salt (to taste)
- Japanese mayonnaise (I recommend Kewpie brand for this dish)
- 1 can tuna (packed in oil, drained well)
For the base and toppings:
- nori seaweed (shredded into strips)
- steamed rice (freshly cooked white rice is best)
- Japanese chili oil (optional, for a spicy kick)
- green onions (sliced thinly)
Step 1: Prepare the Green Onions
Start by finely chopping some green onions to use as a topping.
Set them aside for later use.
This adds a fresh and flavorful garnish to your dish.
Step 2: Make the Tuna Salad
Drain a can of tuna and transfer it to a bowl.
Add Japanese mayonnaise and a pinch of salt to the tuna, then mix well to create a creamy tuna salad.
Taste and adjust seasoning as needed to suit your preference.
Step 3: Assemble the Rice Bowl
Serve steamed rice in a bowl, creating a fluffy base for your toppings.
Layer the rice with shredded nori seaweed, which will add a savory and slightly crunchy texture to the dish.
Step 4: Add Tuna Salad and Toppings
Spoon the prepared tuna salad on top of the nori-covered rice.
If desired, sprinkle the finely chopped green onions over the tuna salad for an optional burst of flavor and color.
This step enhances both the appearance and taste of the dish.
Step 5: Finish with a Flavorful Drizzle (Optional)
For an extra kick of flavor, drizzle with la-yu (Japanese chili oil) over the assembled bowl.
This step is optional but recommended for those who enjoy a bit of heat and complexity in their meal.
Serve immediately and enjoy your simple yet delicious tuna salad rice bowl!
