Warm Steak and Blue Cheese Salad

HEAT 1 Tbsp. of the dressing in large skillet on medium-high heat. Add meat; cook 2 min., stirring constantly.

ADD peppers and onions; cook and stir 5 min. or until meat is cooked through and vegetables are crisp-tender. Stir in remaining dressing.

PLACE 2-1/2 cups of the greens on each of four salad plates. Top evenly with the meat mixture and cheese just before serving.
