Whatever we want. It depends on the family in question, what they're in the mood for, what's part of their diet, what's available, etc.
If you are asking about common staples; there's cheeseburgers, hot dogs, fried chicken, BBQ, etc. However, America is a multicultural country with people from many different heritages. So depending on your family's heritage, you might prefer to other kinds of dishes more often.
Do you like cheese-filled hotdogs/sausage?
