Prep Salmon: Preheat oven to 400 degrees F. Pat salmon dry with clean paper towel. In a small bowl combine soy sauce and chili garlic sauce. Lightly season salmon with kosher salt and ground black pepper. Generously brush on the soy sauce mixture.
Cook Salmon: Bring a large cast iron skillet to medium-high heat. Add oil and swirl to coat the pan. Sear salmon, skin-side up, 2-4 minutes or until nice and browned. Flip over. Turn off stove-top and transfer cast iron skillet to oven, middle rack and uncovered. Let cook 10-14 minutes or until salmon is fully cooked (internal temp reaches 140 degrees F.).
Spicy Mayo: Meanwhile, in a small bowl combine mayo and chili garlic sauce. Taste and add more chili garlic sauce, as desired.
Build Bowls: Divide rice between 4 bowls followed by the salmon, avocado and cucumbers. Add as much spicy mayo as you would like and garnish with furikake. Serve with soy sauce, as desired.
Notes
Gluten-Free: use Tamari as a gluten-free substitute for soy sauce.
Rice: I love using sushi rice here, but feel free to use whatever kind you prefer.
Storage: store leftovers in an airtight container in the refrigerator for up to 3 days.
