I made a tapenade with the following ingredients: kalamata olives, capers, anchovy, garlic, thyme, lemon, olive oil. Although I rinsed the olives and capers (as per the recipe) the result is pretty salty. It's not inedible but would be a lot better if there was something to counter the saltiness even if it doesn't end up tasting like a traditional tapenade. I just want it to be eaten! Any suggestions what I can add? 
My 2 Euro-Cents worth:   Easy - Serve it with something un- or under-salted. Parsley or spinach are great at this sort of thing. You're not eating it with a spoon, so you can add some greens to your sandwich. Medium Effort - Puree some fresh parsley and mix it in. Parsley is famously good at soaking up salt. Note that this will not only change the flavour of your tapenade, but will also significantly shorten how long it can be kept. High touch - Get some more olives, drain them and soak in fresh cold water for a few hours. This will leach the salt out of them slowly. Then chop/puree the olives and mix into the tapenade to balance it out.
