How to Make It
Place a jelly-roll pan in oven. Preheat oven to 500° (leave pan in the oven as it preheats).
Carefully remove pan from oven. Coat pan with cooking spray. Add potatoes to pan; bake at 500° for 10 minutes.
Combine olive oil and next 5 ingredients (through honey) in a small bowl, stirring with a whisk. Sprinkle chicken with 1/8 teaspoon salt and 1/8 teaspoon pepper. Heat a large skillet over medium-high heat. Add canola oil to pan; swirl to coat. Add chicken to pan; cook 5 minutes. Turn chicken over; drizzle chicken evenly with about 2 tablespoons mustard mixture.
Add chicken to jelly-roll pan with potatoes; bake at 500° for 10 minutes or until potatoes are tender and chicken is done. Drizzle potatoes with remaining mustard mixture; sprinkle with remaining 1/8 teaspoon salt and remaining 1/8 teaspoon pepper.
