When I eat lunch with friends, in my home or theirs,we sit at the table and will have a pasta with meat or vegetable sauce for a starter followed by maybe a small piece of meat, fish or cheese with some cooked vegetables or some salad. That may be followed by a piece of fruit. This is accompanied by a crusty bread roll and wine or (more likely) mineral water.
Lunch is followed by a small espresso coffee made in the Moka
If I go out to lunch, as I am retired time is not an issue, so I will aim for the 1pm 'sitting'. From 12-1 is usually the 'early sitting' for those workers who only have an hour for lunch - whereas the 1pm one is for those like shop workers and anyone else who has longer...The 'everyday' meal there will be very similar to that eaten at home. That is quite different to a holiday, weekend or Festa meal...
Thank goodness these family times are still used here and the habit of sitting with a meal on a tray on your knees while watching the television is not a part of mealtimes here. It would be a tragedy if the habit of eating where there is little or no conversation became part of Italian culture. Or everyone having or expecting different meals and mealtimes - what kind of family is that going to hold together?.
