Whole 30 Whole30 Garlic-Ginger Ahi Tuna Cucumber Bowls
These bowls are a serious weeknight win — bold, fresh, and genuinely satisfying without a grain of rice or a drop of soy sauce in sight. Coconut aminos do all the heavy lifting here, delivering that savory, slightly sweet depth you'd expect from a soy-based marinade while keeping everything compliant. The tuna gets a quick sear in a screaming-hot cast iron pan, building a gorgeous crust in just a few minutes per side before being sliced and layered over a crunchy base of shredded cabbage, cucumber, carrots, and radishes. A bright lime-ginger dipping sauce ties the whole bowl together with a hit of acid and toasted sesame that makes every bite feel intentional. One of the trickier parts of eating this way is finding meals that feel restaurant-worthy rather than restrictive, and this one genuinely clears that bar. Serves four, so it's great for meal prep or a casual dinner where everyone builds their own bowl and adds cilantro and sesame seeds to taste.

Instructions
- 1
In a small bowl, whisk together 3 tbsp coconut aminos, the grated ginger, minced garlic, red pepper flakes, and salt to make the marinade. Reserve 2 tablespoons of the marinade in a separate small bowl before adding the tuna — this reserved portion will be used to baste the fish during cooking. Place the tuna steaks in a shallow dish, pour the remaining marinade over them, and turn to coat. Let marinate at room temperature for 15 minutes.

While the tuna marinates, whisk together the sauce ingredients in a small bowl: 3 tbsp coconut aminos, lime juice, toasted sesame oil, grated ginger, and rice vinegar until combined. Set aside.
