Add onions. Cook, stirring occasionally, until tender, 3-4 min. Season with salt and pepper. Remove from heat. Transfer veggies to a medium bowl to cool slightly. Carefully wipe the pan clean.

Pat salmon dry with paper towels, then season with pepper and ½ tsp (1 tsp) garlic salt. Reheat the same pan over medium-high. When hot, add ½ tbsp (1 tbsp) oil, then salmon, skin-side down. Cook, flipping once, until golden brown and cooked through, 5-7 min.**

Meanwhile, add tomatoes, half the cilantro, half the lime zest, ½ tsp (1 tsp) sugar and ½ tbsp (1 tbsp) lime juice to the medium bowl with veggies. Season with salt and pepper, then stir to combine.

Fluff rice with a fork, then add remaining lime zest and 1 tbsp (2 tbsp) butter, stirring, until melted, 1 min. Divide rice between bowls. Top with salsa and salmon. Drizzle chipotle sauce over salmon. Sprinkle with remaining cilantro.
