01 - Pat salmon fillets dry with paper towels, then season both sides evenly with salt and ground black pepper.
02 - Heat vegetable oil in a non-stick skillet over medium-high heat. Place salmon fillets skin-side down and sear for 4 to 5 minutes, until the skin becomes crisp. Flip salmon and cook for an additional 2 to 3 minutes, or until fully cooked. Transfer fillets to a plate and let rest.
03 - Add thinly sliced garlic to the same skillet and sauté over medium heat until golden and crisp, about 1 minute. Remove garlic with a slotted spoon and drain on a paper towel.
04 - Wipe the skillet clean and add a small amount of vegetable oil if needed. Spread cold, cooked rice evenly in the skillet and press lightly to compact. Cook undisturbed over medium-high heat for 5 to 7 minutes, until the underside is golden brown and crispy.
05 - In a small bowl, whisk together mayonnaise, Sriracha, lime juice, and toasted sesame oil until smooth and creamy.
06 - Divide crispy rice evenly between two serving bowls. Top each with large chunks of salmon, kimchi, cucumber slices, avocado, and chopped scallions. Drizzle spicy mayo over the top, then garnish with crispy garlic, toasted sesame seeds, and nori strips if desired.
07 - Serve immediately while warm.
