Over the past year we've made it the norm in our family that we have a salad with most dinners (some dinners don't really work well with a salad, so this rule is more general than absolute). We buy big tub things of mixed greens (Fortinos, a local branding of Loblaws - I think they made an Italian sounding name to pander to the nearby Hamilton market - has an awesome very high quality, organic, already cleaned tub with something like 2KG of mixed greens for ~$5. With proper storage it lasts for about a week), and then add in some cut green onions, grape tomatoes, cucumbers, and whatever else tempts our taste buds that night.

The health benefits are unquestionable, but more importantly it's an epicurean delight.

It is remarkable how accessible, and inexpensive, such quality-of-life improvements really are.
