I, like Suzanne, am shameless and cheap, and I RARELY if ever throw anything away. I scrape mold, I spoon mold and slime, I heat to kill anything I've missed, and I make sure I eat what I buy. A couple of months ago, I was on a sort of quesadilla kick, and ran out of tortillas. While waiting for them to go on sale, my refried beans and my salsa got a bit of the green stuff. I took off what I could see, and threw them into the freezer. I just bought my tortillas and defrosted the two items, MIXED two items in a pot, heated for a good while, and ate my yummy quesadilla again. Never gotten food poisioning ever, and I really push it with "spoiled" food.
