Meanwhile, in 12-inch nonstick skillet, cook sausage, bell pepper and onions 8 to 10 minutes over medium-high heat, stirring occasionally, until vegetables soften and begin to brown and sausage is no longer pink; drain. Return to skillet; stir in milk, green chiles and remaining 1 tablespoon taco seasoning mix. Heat to boiling over medium-high heat. Reduce heat; simmer 2 to 3 minutes or until thickened. Pour mixture over quinoa mixture in baking dish.
