In my efforts to become a more healthy (and fiscally responsible) individual this year, I've been trying to make salads at home for dinner and lunch.

My problem? I hate store-bought salad dressings. I've found a few refridgerated kinds that I like, but I'm tired of shelling out 4 bucks for something that I'm guessing is relatively easy to make.

Does anyone have any recipes for good salad dressing? My tastebuds, tummy, and wallet appreciate it.
