As a busy career woman and single mother of 3, I have learned to plan ahead and cook big meals that leave leftovers for the week and freezing for meals later in the month or next month. For example, last night I cooked a double batch of chili and a double batch of cornbread muffins. Extras will go in the freezer. I made healthy protein bars that make for a healthy breakfast or snack as well. I also made breakfast muffins and froze them so the kids can grab one or two for breakfast. So 4 hours of cooking last night and now I don't have to cook for a few days other than small sides.
