I think this is what you are looking for:

I use it all the time. Copy/paste your recipe (no need to look up food by food) and it will calculate things for you. It is the least tedious to use, I think. I have found, though, that with certain foods it picks really strange equivalencies - like, I made something with some mayonaise, and it put in salad dressing. So I had to go and put in an actual brand name for it to find the right food.
Try it and see if you like it!
