Oval Cake Pan How Much Food Is Wasted At Your House?

How much food is wasted at your house? - oval cake pan

The reason I ask, by the amount of leftover food appauled that my mother in law house this weekend.
Here's what was left after packing everything that my husband and I have eaten this week:

1 / 4 lg. Pot Vegetable Soup
1 chili pepper LG Oval Slow Cooker
9x13 pan (single layer) piece of fried chicken
SM 6.7. Pork chops into thin slices
6 cups mashed potatoes, instant
3 cups potato chips
1 slice of lemon cake large

I grew up, just enough for all the cooking during dinner used to destroy what in the fridge first and eat the remains of lunch. Maybe I'm strange, but it seems to eat too much before they sold.
