i would suggest the same thing! slow cooker is your best friend - and you make a huge variety of things!!

i've spent the past couple of weekends cooking meals in the slow cooker for DH for work (almost filled the freezer woo hoo!!) - soups are pretty easy, spag bol (we par cook the pasta, and throw it in once it's almost finshed cooking - flavour goes through - can reheat as is, or make into a pasta bake with cheese on top. same deal with chicken in bolgnaise sauce - makes AWESOME pasta bake!! any sort of casserole (slow cooker is awesome!! didi i say that already??)

depending on what you like (and how much room you have) - vegie soups are always good. this weekend i made 6L of vegie soup (pumpkin base, but lots of extra veg, hint of garlic and curry - i can't do plain pumpkin soup!). bulk things that are normally fiddly if you're making them in small lots (like veg in cheese sauce - cook in bulk, freeze in meal sized portions..)

ummmmmm, i'm sure other ladies will suggest some stuff - i've just listed when i've been doing in the last couple of weekends!!!
