01 - In a bowl, combine rice vinegar, sugar, and salt. Add carrots, cucumber, and radishes. Toss and let sit for at least 20 minutes, stirring occasionally.
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, 5 minutes. Fluff with a fork.
03 - In a small bowl, whisk together soy sauce, mirin, honey or maple syrup, rice vinegar, sesame oil, ginger, and garlic for the teriyaki marinade.
04 - Place salmon fillets in a shallow dish or ziplock bag. Pour half of the marinade over the fish and marinate for at least 10 minutes (up to 30 minutes). Reserve the other half.
05 - Preheat oven to 400°F or heat a nonstick skillet over medium heat. Remove salmon from marinade and place on a foil-lined baking sheet or in the skillet. Bake or cook for 10–12 minutes, until salmon is just cooked through and flakes easily.
06 - Pour the reserved marinade into a small saucepan. Bring to a simmer over medium heat. If desired, mix cornstarch with 1 tbsp water and stir in to thicken. Cook for 2–3 minutes, until glossy.
07 - In a small bowl, mix mayonnaise, sriracha, and lime juice until smooth.
08 - Divide rice among four bowls. Top with flaked or whole salmon, drained pickled veggies, avocado slices, scallions, sesame seeds, cilantro, and nori strips. Drizzle with teriyaki sauce and sriracha mayo.
