Pinterest has made it really easy for me to vary my menu plan. I have made boards for different cuisines:
Mexican/Southwest, Italian, French, Indian/SouthEast Asian, Cajun etc... so now when I pin an ethic dish I put it with it's type of cuisine. For instance, if we feel like Asian one night, I have a selection of recipes to choose from.
I have also made seasonal boards. When I find a great fresh produce item at the green market I usually have pinned a few dishes I can use it with so it doesn't wilt away in the bottom of my fridge while I try to figure out what to do with it.
Take a look at my pin boards to get some ideas on how you would like to organize your recipe pinning for more interesting dinner planning, and please by all means follow me on Pinterest too.
