Step 1: Prepare the Quick-Pickled Vegetables : In a medium bowl, combine rice vinegar, sugar, and salt. Stir until dissolved. Add the carrots, cucumber, and radish to the mixture. Toss to coat and let sit for at least 15 minutes, stirring occasionally. Drain before serving, or keep them slightly soaked for a stronger tang.
Step 2: Make the Teriyaki Sauce : In a small saucepan, whisk together soy sauce, honey, rice vinegar, sesame oil, garlic, and ginger. Bring to a gentle simmer over medium heat. In a small bowl, mix cornstarch and water, then stir it into the sauce. Cook until the sauce thickens and becomes glossy, about 2–3 minutes. Remove from heat and set aside.
Step 3: Cook the Salmon : Pat the salmon fillets dry and season lightly with salt and pepper. Heat olive oil in a large nonstick skillet over medium-high heat. Add the salmon fillets and cook for 4–5 minutes per side, depending on thickness. Once the salmon is nearly cooked through, pour half of the teriyaki sauce over it. Let the sauce bubble and coat the salmon, forming a shiny glaze.
Step 4: Assemble the Rice Bowls : Divide cooked rice evenly among 4 bowls. Top each with a piece of glazed teriyaki salmon. Add a generous portion of pickled vegetables on the side. Drizzle additional teriyaki sauce over the top. Sprinkle with toasted sesame seeds, green onions, and cilantro.
