01 - Combine rice vinegar, sugar, and salt in a bowl. Add carrots, cucumber, and radishes. Toss well and let sit for at least 20 minutes, stirring occasionally to evenly distribute flavors.
02 - Rinse jasmine rice until water runs clear. Combine rice, water, and salt in a saucepan. Bring to a boil, cover, reduce to low, and simmer for 15 minutes. Remove from heat and let stand covered for 5 minutes. Fluff with a fork.
03 - Whisk together soy sauce, mirin, honey or maple syrup, rice vinegar, sesame oil, ginger, and garlic in a small bowl until well combined.
04 - Place salmon fillets in a shallow dish or resealable bag. Pour half the marinade over the fish. Marinate for at least 10 minutes, up to 30 minutes. Reserve remaining marinade for sauce.
05 - Preheat oven to 400°F or heat a nonstick skillet over medium heat. Remove salmon from marinade and place on foil-lined baking sheet or in skillet. Bake or cook 10-12 minutes until salmon is just cooked through and flakes easily.
06 - Pour reserved marinade into a small saucepan. Bring to simmer over medium heat. If desired, mix cornstarch with 1 tbsp water and stir in to thicken. Cook 2-3 minutes until glossy and slightly thickened.
07 - Mix mayonnaise, sriracha, and lime juice in a small bowl until smooth and evenly combined. Adjust sriracha amount to taste.
08 - Divide rice among four bowls. Top with flaked or whole salmon, drained pickled vegetables, avocado slices, scallions, sesame seeds, cilantro, and nori strips. Drizzle with teriyaki sauce and sriracha mayo. Serve immediately.
