No, that wasn't the one - here's the one from the magazine (I'm not real crazy about onion soup mix in meatloaf, myself. - but, the corn idea sounds good

)
Skinny Meatloaf with sweet-&-sour ketchup
makes 12 3/4"-thick slices
Combine:
1/2 lb. each: ground sirloin (85% lean) I used 80/20, ground pork and ground turkey
1 cup panko or fresh bread crumbs
1/2 cup chopped fresh parsley
1/4 cup onion, grated
2 egg whites
3 T. 2% or skim milk
1 T. worcestershire sauce
salt & pepper
Stir together; top meatloaf with:
1/3 cup ketchup
1 T. prepared yellow mustard
2 tsp. brown sugar
Preheat oven to 350 F.; coat a broiler pan with nonstick spray (I used a loaf pan - better for sandwiches, imo)
Combine ground meats, crumbs, parsley, onion, egg whites, milk, worcestershire, salt & pepepr in a bowl, using your hands to mix.
Transfer the mixture to the prepared pan, shaping it into a 9X5" loaf.
Stir ketchup, mustard and brown sugar together in a bowl, then spoon on top of the meatloaf. Bake until meatloaf reaches 160F. on an instant read therm., about 1 hour. let rest at least 5 minutes.
