On weekends, make a couple of big meals for the week. Right now, we have a sausage and lentil soup on the stove (two meals for two, at least), and a veggie-heavy bolognese sauce for lasagna. We'll assemble the lasagna tomorrow and that will see us through for four meals for the two of us, taking us through to Thursday.
Other weeks, we also make our own version of chana masala (chick peas in a curry sauce, with loads of veggies). Or we make a big pot of chicken noodle soup. Or, a big pot of stew.
Making two big meals at once is great because you can do all the washing and chopping at the same time. The veg base for both meals today was onions, celery, carrots, red peppers, garlic.
(We are in the midst of an ice storm today - sleet, snow and freezing rain. Temps are -4 Celsius, feels like -11 C with the wind. So we are still into the winter food, even though we live in Southwestern Ontario where we should be well into Spring, FFS.)
In the summer, we will grill up twice the amount of chicken we'd normally eat, and make either a pasta with chicken and veg the next day, or a chicken salad.
When you cook your own food, you have more control over what you're eating. You control the fat and sodium, spices etc. and minimize or eliminate the nasty stuff (additives and preservatives you can't pronounce, antibiotics/pesticides if you buy organic, etc.).
If we ever make too much of something, we freeze it.
As an added bonus for motivation, the restaurants and take-out places are all overpriced and shite, so cooking at home is a no-brainer.
