Melt the butter in a medium frying pan either on the stove or on the grill.
Fry the chicken until tender. Chop up the green peppers, onions, and tomatoes and add the oregano and pepper to taste (about 1 tablespoon of each).
Pour this over the chicken and cook about 20-30 minutes until marinated in the sauce it makes.
Top with the cheese and let it brown. Umm umm good!
