Substitute extra-lean ground beef for the sausage and 1 thawed 10-oz. pkg. frozen chopped spinach for the peppers. Squeeze spinach to remove excess liquid before adding to cooked ground beef and onions with the spaghetti sauce and oregano.
Enjoy this flavorful lasagna with a mixed green salad tossed with your favorite KRAFT Dressing.
Spraying the foil with cooking spray before using to cover the lasagna helps prevent the foil from sticking to the cheese on top.
