I was doing this exact same thing for awhile, and ever since October my business has put all regular workouts and eating big on hiatus for awhile. It's killing me not to eat and lift big, but building the business is more important right now.
Sundays I made thick beef and chicken stews. These were some of the best things I ever tasted, full of tender meat and flavor, but eating stew like 4 times a day is bad for business. It's messy and a pain in the ass to heat up and eat quickly. In a couple months when I ramp up the eating again, I will return to the Sunday cooking marathons, so this is a good discussion topic.
Freeze anything that won't be consumed in the next 48 hours. Not because it's going to kill you to eat week old leftovers, but this way the food stays at maximal freshness, and you anything you can do to avoid getting sick of eating the same thing all week is a good thing. Variety is a good thing to, so long as all your meal creations are of similar quality. What I've found from cooking your weekly rations en masse is that you really have to consider how your body/mind will react to eating the same foods frequently. You don't want to make 3 different types of meal for the week, and find that one of them is by far better than the others, or you'll eat it right away and get bored quickly with the inferior tasting meals. Silly as it sounds, the trade-off for mass production is a lack of variety, and it's something to keep in mind when Sunday rolls around. I wish my life was simple enough that I could grill a new meat and play Iron Chef every day, but that's not the case.
Some other tips...
- Cut meat into bite size pieces before cooking. Some meat shears will make it easy.
- Moisture retention is very important, so make meals that are very moist to begin with.
- Use bold seasonings and flavors, because often they tend to diminish after storing.
- Cram as much food as you can into those little containers.
- Get really creative with your containers of vegetables, because if you're eating big you're going to want (and need) to eat a lot of them
