So, what I think is a really good option is buying fresh ingredients to make something that will last a little while in the fridge.
Like...
butternut or acorn squash, carrots, turnips, apples...
squash in the microwave for a few minutes, then put everything on a cookie sheet, sprinkle with EVOO maybe some salt, pepper, cinnamon, roast for 10 min.s
heat up some chicken broth
put all the roasted stuff in a blender with a couple pieces of ginger, pour into the chicken broth and there's soup for the week!
Last Sunday I made some turkey chilli which is basically turkey, tomatoes, peppers, onions, a little bit of garlic, and spices and, again, good for the week!
It's an inexpensive and easy option that is also healthy.
I think the most important thing is not eating anything processed. What, 70% of our immune system is in our gut? People don't realize the damage they do by ingesting all the chemicals in the majority of our food. It's why there's so much food allergies now a days... and cancer, and most other illnesses as well.
I mean, I'm not a nut about it... I just ate an entire pack of graham crackers... but starting TOMORROW, no more processed food. Startiiiiing... now!
