I just replied to your other thread, but since you already have a little food processor, my response is moot! :) The only thing I could think of that would need straining is sweet potatoes, which are sometimes stringy. Once it's cooked, you could push the potatoes (if they are stringy) through a regular strainer to remove the strings. I can't think of anything else I've strained. I actually used a ricer for DD's sweet potatoes, but I already had one.
