I'm assuming you're on a budget and want to minimize kitchen and prep time. One way to do it is to bulk cook and freeze meals. I do that with my crockpot chicken stew, bulk cooked and frozen into about 50 individual meals at $1.25 apiece
which I later eat "as is" or doctor into various meals like burritos, soups, sloppy joes, Indian or asian fusion:
Bulk cooked it comes out to $1.25 per meal because I wait until my local store marks down their chicken breast to $1.99/lb. This makes for individual containers of chicken breast, brown rice (or quinoa), black beans, lentils, various root vegetables and spinach leaves. Base ingredients:
$25 boneless skinless chicken breast @ 1.99/lb (wait for a sale if need be to bulk cook and fill your freezer)
$25 various diced root vegetables, whatever's available: yucca, yam, parsnip, onion, carrots, butternut squash, rutabaga, leeks
$10 various: black beans, brown rice, quinoa, chicken broth, spinach leaves
I'm not counting the cost of the freezer chest, which was $150.
Soak and crockpot cook black beans and lentils from scratch and put aside. Then dice (also if you're inclined, brine and pound beforehand) chicken breast. Slow cook the chicken with a little low sodium broth, water and the root vegetables and you'll find that the veggies will develop the taste and texture of potatoes, so if you like chicken and potatoes you'll love this. Make brown rice and quinoa. Assemble your cooked stew, black beans and lentils, cooked brown rice and quinoa and spinach leaves and portion into individual food containers and freeze. Relatively unspiced, use it as a base as chicken stew, add cumin and chile pepper and put in an Ezekiel wrap and top with plain yogurt and salsa for burritos, add broth to make hearty chicken soup, add with Thai sauce and and unsweetened canned chunk pineapple to asian noodles, spread hot on a spelt roll as a sloppy joe or cold as a chicken salad, or add a Tasty Bite brand flavoring packet with a sliced banana and raisins for Indian.
