More than I'd like to admit, maybe 3-4 times for supper and a couple of lunches. Honestly though, the 3 of us have vastly different tastes in food and it's much easier to pick up what each person wants than to try and find one meal that we'll eat.
And have you priced making a meal at home? It costs a fortune to make tacos and they're what, 2$ at Taco Bell?
