There are some items I will buy canned, but in general I prefer frozen in most cases when fresh is either not available, or not in my budget. I'm surprised some people on here mentioned that they will buy canned peas though - those are like the epitome of what I don't like about canned food - greyish, bland, briney, mushy and taste like mouth full of preservatives. Frozen peas are not only cheaper by weight, they are fresher tasting and don't have any preservatives and they just freeze well naturally. That's kind of a no-brainer as far as I'm concerned. I can tolerate some brands of canned corn, if they are the kind packed with little to no liquid. They come in handy if I am making a dish with corn on it, such as a southwestern chicken salad, and I don't necessarily want completely raw corn, but I don't feel like spending the time cooking fresh corn and waiting for it to cool down either. Canned beets are another one I don't mind and actually prefer them from a can. They're far too messy and time consuming for me to cook them from fresh, and no matter how careful I am I almost always end up staining clothing and other kitchen stuff permanently. Generally I eat them room temperature tossed in a sweet vinaigrette, so I will just drain them from the can, rinse them, and blot them dry then dress them with the vinaigrette.
