Yeah, cooking ahead would be preferable, but her plea made it sound like she might not even have time to do that.
Oh yeah, Trader Joes. Another good idea. Don't get the potstickers, though. They were disappointing. Better ones available at the Asian market.
DH likes to make big pots of stuff too -- some for now, and some for later sort of thing. Another quick dinner that DH likes to make is pizza -- he'll prepare 6 batches of dough at a time (we have a kitchenaid so the main hassle is waiting for it to rise), then he wraps them individually and throws 'em in the freezer. All he has to do later is pull out a ball to defrost, stretch it out, put whatever toppings on it and pop it in the oven.
(As you can tell, DH is good about making sure I'm well-fed... unfortunately, I weigh five pounds more now than I used to because of it! Burp!)
