I cook all my meals on sunday (or a free day) and freeze them. While I am doing the laundry and cleaning the house, I am "power cooking"!
Spaghetti, beef, chicken, soup, grilled burger patties.... It all frezzes and tastes yummy.
I even cook up my veggies and rice and place them in individual packets. They last in the frezzer if you squeeze all the air out before you zip up the plastic baggie. One trick is to place all the seperate food boogaie into another Ziploc bag and you ahve double protection.
I have food this is much more convenient than fast food. I don't have to stop at the drive thru when I just want to go home, packing my lunch takes two secs and I can throw my dinner in the micorwave while I am doing other things.
If you can't cook buy yourself a wide variety of frozen dinners. Stoffers makes the BEST chicken Lasgna. They even have "healty" microwave dinners (but I think all of them have too much salt). Some of them even kids will like.
Frozen dinners, milk, instant oatmeal, fresh fruit, coffee... Your shopping list is complete!
