Food that you like, most of it not processed crap. Good protein sources. Here's things I buy, although more like over a month than a week since I tend to buy my meats at CostCo and freeze for later.
Extra lean ground meat (turkey/beef/pork/whatever - 93/7)
Chicken breasts
Beef - sirloin, roast, maybe a ribeye
Frozen tilapia loin - with lemon pepper this is great
Tomatillos
Frozen diced onions
Fresh okra
Kale
Barilla Plus pasta - I like angel hair, don't eat it every week
Beans - chickpeas, black beans, great white northern
Fresh asparagus - and lots of it. The one veggie my husband will always eat.
Milk 1 or 2%
Cheese, both full fat cheddar for snacks as well as reduced fat Mexican for cooking
Greek yogurt
Cottage Cheese
No fat and reduced fat cream cheese
Great Western Bagels (high fiber, high protein, low calorie)
Acorn squash - stays good for a long time, so no worries if you don't eat it right away
Frozen fruit - good mixed in with the greek yogurt
Splenda with fiber as well as other fake sugars.
Steel cut oats / Irish oats
