How to Make It
Preheat oven to 400°F. Rub chicken thighs with 1/2 tablespoon of the canola oil, and place on an aluminum foil-lined sheet pan or rimmed baking sheet. Sprinkle with 1 teaspoon of the salt and 1/2 teaspoon of the pepper. Bake in preheated oven until a meat thermometer inserted in the thickest portion of chicken registers 165°F, about 35 minutes.
Meanwhile, stir together orange marmalade, soy sauce, vinegar, mustard, and sesame oil in a small saucepan. Bring to a simmer over medium, and cook, stirring often, until slightly thickened and reduced to about 1/2 cup, about 8 minutes. Set aside. Toss green beans with chili-garlic sauce and remaining 1 tablespoon canola oil, 1/2 teaspoon salt and 1/4 teaspoon pepper in a large bowl.
Increase oven temperature to broil. Brush orange marmalade mixture on chicken thighs, and spread green beans around chicken. Broil until green beans are tender and chicken is browned and glazed, about 3 minutes.
