I haven't had produce in a bag in about 5 years. And even when I purchased lettuce in a bag, I washed it. Even though it says prewashed. Because, I guess, I could be a little OCD.
Lettuce is filthy. Spinach is sandy. You just can't wash that shit enough. But yeah, I almost bought spinach last week for a salad. Then I decided ravioli sounded better. Yay, no e-coli here.
