In this insane Minneapolis winter, I've taken to always tossing some extra, removable clothing layers in my backpack before I leave the house - stuff that's light to carry, but will maybe make the difference between freezing into a human icicle at the bus stop, and not. I usually carry a thin long-sleeved undershirt, an earband, leg warmers (if I'm not wearing them!), arm warmers, maybe a hat, maybe another scarf. Knowing I have these available makes me more willing to brave the outdoors.
Because I'm not cooking for a family, it's easy for me to just get take out every night. Instead, I buy lots of healthy meat when it is on sale. I then package it in individual proportions, some of it sliced, some of it cubed, and others as a half breast. Then, when I leave for class in the morning, I just throw one package in the fridge and when I get home it is defrosted and ready to be cooked however I see fit.
Fill various sized bottles and jugs half full of water. Place bottles (not gallon jugs) so that they lean (keep stable) to one side while freezing (without lids). Keep gallon jugs upright (also no lids). When ready to use fill with fresh water and screw lids on snuggly and you're all set to go!
Starting a garden is a great way to get some exercise, get some healthy veggies to eat and in the end you'll have a sense of accomplishment that will motivate you to do more!! Learn to can or freeze the extras at the end of the season and you can enjoy your garden year round!
I use my slow cooker to cook a full batch of veggie broth soup starter with beef, onions, and black beans.
