How to Make It
To prepare dressing, grate 1 teaspoon rind; squeeze 1/3 cup juice from orange over a bowl. Set rind aside. Combine juice, vinegar, and next 4 ingredients (through chile sauce) in a small bowl; stir with a whisk.
To prepare salad, heat 2 teaspoons canola oil in a large nonstick skillet over medium-high heat. Add bell pepper and carrot to pan; sauté 1 minute, stirring occasionally. Add reserved orange rind, sugar snap peas, and salt to pan; sauté 2 minutes, stirring occasionally. Transfer pea mixture to a large bowl; cool 5 minutes. Stir in green onions and spinach. Pour dressing over salad; toss gently to coat. Sprinkle with sesame seeds. Serve immediately.
