In small bowl, mix butter, chili sauce and hot pepper sauce.
In large bowl, mix chicken and half of the chili sauce mixture. In 10-inch nonstick skillet, cook chicken over medium-high heat 8 to 10 minutes, stirring frequently, until well browned and no longer pink in center.
Add remaining half of chili sauce mixture; toss to coat. Serve chicken with toothpicks and blue cheese dressing for dipping.
