Deluxe Cheeseburger Salad

This is a recipe I found on the Pampered Chef website.

4 sesame seed hamburger bun tops
1 small red onion, divided
2 plum tomatoes (I used 1 regular tomatoe)
¾ lb 95% lean ground beef (I used 1 lb of ground beef)
½ cup finely diced dill pickles
¾ cup ketchup
1 tbsp yellow mustard
8 cups thinly sliced romaine lettuce (I used iceburg lettuce)
1 cup (4 oz) shredded cheddar cheese

Preheat oven to 425°F. Slice bun tops into ¼-in. strips (if bun tops are very thick, slice bottoms off horizontally before slicing into strips). Arrange in a single layer on pan; bake 8-10 minutes or until lightly toasted. Remove to cool completely.

Slice half of the onion crosswise into thin rings. Dice tomatoes. Set onion and tomatoes aside.

Cook ground beef until no longer pink. Chop remaining onion. Finely dice pickles. In large bowl, combine chopped onion, pickles, ketchup and mustard. Add cooked ground beef; mix well.

To serve, arrange lettuce on large serving platter. Spoon beef mixture over lettuce. Top with cheese, tomatoes and sliced onion. Arrange hamburger bun croutons around edge of platter. Serve immediately.
