Prepare all the fruit by peeling, coring (if necessary) and cutting it into chunks or slices as desired.
Toss together in a large bowl with the lemon juice (to keep it from discolouring); or you can arrange the different fruits on a large platter and use the tofu dressing as a dip.
Rinse the tofu well and dry thoroughly between several layers of paper towels or clean cloth towels.
Break the tofu into small pieces and put in your blender or food processor.
