Step‑by‑Step Instructions for Spicy Tuna Bowls with Cauliflower Rice
Step 1: Steam Cauliflower Rice
Begin by steaming your cauliflower rice in a pot or steamer basket over medium heat for 5–7 minutes, until it's tender and fluffy. The cauliflower should turn translucent and lose its raw crunch. Once ready, remove it from heat and drizzle with seasoned rice vinegar, tossing gently to incorporate the tangy flavor throughout.
Step 2: Portion Base
Once your cauliflower rice is seasoned, divide about 1 cup of it into meal prep containers. Fluff the rice with a fork to keep it airy and light. This will serve as the delicious base for your Spicy Tuna Bowls, ensuring a satisfying texture that will hold up well against the creamy tuna mixture.
Step 3: Prepare Tuna Sauce
In a mixing bowl, combine mayonnaise, sriracha sauce, and optional toasted sesame oil. Stir the mixture vigorously until it becomes creamy and well-blended. Take a moment to taste it and adjust the sriracha to your desired spice level. This sauce will add a delightful kick to your Spicy Tuna Bowls while binding the ingredients together.
Step 4: Combine Tuna
Carefully fold the well-drained canned tuna into your creamy sauce, ensuring each piece is fully coated. Use a spatula to mix gently so the tuna remains chunky and flavorful. This step creates the star of your Spicy Tuna Bowls, offering a rich and spicy profile against the tender cauliflower rice.
Step 5: Assemble Bowls
Layer the prepared tuna mixture over the seasoned cauliflower rice in each container. Make sure to distribute it evenly to create a beautiful presentation. The vibrant colors and textures will make these bowls irresistible, highlighting the harmony of flavors throughout the Spicy Tuna Bowls.
Step 6: Add Fresh Ingredients
Top each bowl with sliced Persian cucumber for a refreshing crunch, drizzle with additional sesame oil if desired, and sprinkle toasted black and white sesame seeds over the assembly. Finally, add chopped green scallions for a pop of color and an extra layer of flavor, making your Spicy Tuna Bowls not only delicious but visually appealing as well.
Step 7: Storage
Cover the containers with lids and refrigerate your Spicy Tuna Bowls for up to 3 days. If you plan to heat them before serving, remember to add fresh toppings like cucumber and scallions afterward for that crisp, refreshing bite. These bowls make an excellent grab-and-go meal option that is both healthy and satisfying!
