the best timesavers for busy families

As I mentioned here, I've just signed up for The Fresh 20. But I'm curious - what other timesavers are out there? What have you tried and had success with?

Here are a few ways I try to simplify my workload:

• On Sundays, I often cook up a big batch of chicken thighs in the slow cooker, divide it into meal-size portions and stick it in the freezer. Then, during the week, I can grab a jar of pre-cooked chicken and have dinner on the table much faster.
• I also sometimes like to prep meals for the week on Sunday. On a hectic weekday evening, it feels like a miracle that the veggies are already cut and waiting for me in the fridge.
• When cooking, I try to minimize the number of items that have to be washed by hand. For example, I mix up scrambled eggs in a cereal bowl or mug that can go in the dishwasher instead of a mixing bowl.
• I use the vacuum for cleaning all the floors, even the tile, instead of sweeping.
