Tzippi, you eat a lot of eggs! We go through about a dozen a month (but we dont eat too many kugels – I like my veggies in a more natural state).
Also, find out if anyone you know has a costco membership – certain things are much cheaper there (but you have to know prices). Cottage cheese is really cheap. Remember though things come in big tubs so you have to go through a lot. Colored peppers are REALLY cheap there (I think red/yellow/orange are $1.99/lb) but you have to look at the packages. Some come from Israel (others are holland or mexico).
