(7-1/4 oz.) KRAFT Mac & Cheese
extra-lean ground beef
finely chopped onions
dry bread crumbs
(8 oz.) KRAFT Shredded Sharp Cheddar Cheese, divided
HEINZ Tomato Ketchup
Heat oven to 350ºF.
Prepare Dinner as directed on package.
Meanwhile, mix meat, onions, bread crumbs, egg and 2 Tbsp. A.1. just until blended. Divide meat mixture in half; pat each half into 10x8-inch rectangle on sheet of parchment paper.
Reserve 1/2 cup cheddar. Mix remaining cheddar with Dinner; spread over meat mixture, starting at one short end of each rectangle and spreading to within 3 inches of opposite end.
Roll up each rectangle, starting at Dinner-covered end and removing parchment as meatloaf is rolled; press ends and edges of meatloaf together to seal. Use parchment to transfer meatloaves, seam sides down, to 2 (13x9-inch) pans sprayed with cooking spray. Discard parchment.
Bake meatloaves 25 min. Whisk ketchup and remaining A.1. until blended; spoon over meatloaves. Sprinkle with reserved cheddar. Bake 10 min. or until meatloaves are done (160ºF). Let stand 10 min. before slicing to serve.
