On weeks when I "wing it" I find I spend a LOT more on groceries and we tend to not eat as healthy. If I can plan a couple weeks meals in advance I can save a bundle. I buy in bulk at Sam's what I can, the rest I pick up at the grocery store, and we eat fairly well. This past week we had a beef roast, then used the leftovers as BBQ'd beef sandwiches. We did homemade vegetable soup and sandwiches one night, then soup and french bread the next night. I'm getting double nights out of most meals, meaning I'm only cooking roughly half the time. Spagetti is easy because I make extra sauce when I make it, then freeze it in portions....when we're having spaghetti, I pop the sauce in the micro to defrost it, boil noodles, and we're done! For about $2 for our family of 4 too!!
