You could serve this as a 1st course for company; it is not your usual mayo/tuna salad. The addition of fresh mushrooms and green peas really does the trick. I usually make a lighter version where I will strain the whey out of some plain yoghurt in a sieve and use 1/3 strained yoghurt and 2/3 mayo. If using this method the yogurt must be drained really well. I add the peas when they are still frozen; they thaw quickly and I like them cold in the salad and they do not get mushy
