the other day i was at costco with my sister and i found a great box of spinach. the thing is, i'm really the only one who likes spinach, and because we're talking COSTCO, it was big. what to do? she had a great idea; steam the spinach and freeze it for later use. awesome! i packed it into an ice-cube tray, then when they were frozen (overnight) i took them out and put them in a bag for later use. i can pull out a cube or two when i want to add them to spaghetti sauce, eggs, or whatever.
