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. Serve immediately.
