We've reduced it by quite a bit, we used to go out to eat a few time a week, now we're down to a few times a month, typically limited to pizza, burgers, sushi, or Asian food (Vietnamese, Thai, Indian). We like to try new places out, see how their version of our favorite foods tastes. We also go out to eat when my parents invite us out, or when we're traveling.
The majority of our meals are cooked at home though. I make breakfast fresh every morning (3 eggs + 2 slices of bacon or a quarter cup Mexican chorizo), and we take a few hours on the weekends to prepare all of our lunches and dinners for the week. Leftover food that's handled safely (quickly cooled after cooking) will make it from Saturday's cook time to Friday's dinner just fine in the fridge, but we will freeze if we make too much. Restaurant / fast food meals are simply not large enough to fuel us; I eat 8 oz of protein per lunch/dinner, a cup of starch, and a cup of veggies, wife eats 6 oz protein, 1/2 cup of starch, and a cup of veggies. To get this amount of food would be insanely expensive most places.
