I LOVE Aldi's!! the quality & selection has steadily improved over the years & I buy pretty much everything I can there now. The total is consistently HALF what I would spend for the same stuff at the regular store.
Currently my favorite cheap cheap cheap meal is chicken ramen noodles w/ a whole lot of frozen stir fry veggies thrown in with it. Very filling, not too bad health-wise, and delicious!! (at least, to me.)
