Boy I'm right there with you! I can't say I hate cooking, but my wanting to cook comes in spirts.
When I'm in the mood I will take a weekend and cook, cook, cook. I decide usually on Thursday what I want to eat the next week, shop for it on Friday afternoon and start cooking Friday night, usually by the end of Saturday I've cooked enough for a small army, I divide it up, put it in freezer bags and pack the frig and freezer for the upcoming week.
When I'm not in the mood I rely on rotisserie chickens and veggies (fresh) all week, I've even had to purchase lunch meats and cheese (I try to stay away from cheese as much as possible).
This week I am relying on bagged skinned chicken breast, I get up early pop two of them in the microwave, tear up lettuce (making sure to be generous with the Olive Oil I put on it) pop it in a large Ziploc bag with black pepper pack my Apple Cider Vinegar and out the door I go.
I agree, if I don't pack something for lunch I can kiss all my progress goodbye, so easy to order out during lunch at work...and unless I'm ordering chicken wings with no sauce (so much fat
) I can easily slip off plan
