Preheat oven to 375°

Chop bell pepper and onion then add 2/3 to large mixing bowl

I used the "As Seen on TV StuffT" burger stuffer but you could use the bottom of a round glass to form your burger cup.

After forming cup spoon cheese mixture into void and top with burger lid

Arrange on broiling pan (I could only fit six on my pan so had to cook the last 2 after the first batch)

Bake in oven at 375° for 45min or until burger meat internal temp reaches 165°

Allow to cool before serving or storing
