Shape meat into eight thin patties. Spoon 1 Tbsp. of the chilies onto center of each of four of the patties; top each with second patty. Pinch edges of patties together to seal.
Cook in nonstick skillet on medium-high heat 6 to 8 min. on each side or until cooked through (160F). Top with VELVEETA; cover. Cook an additional 30 sec. to 1 min. or until VELVEETA is melted.
