I have been making fruit salads this way for years with a slight variation - I use canned fruit in the winter - diced pineapple and canned mandarin oranges. I drain off the liquid and save it. Then, in a large bowl I put the instant vanilla pudding mix and I use a little of the canned mandarin orange juice until it is "melted" and then I add the sliced bananas - seems to help in keeping them from browning so quickly. We also use miniature marshmallows added at the very end. Any kind of fruit - fresh, canned or probably even frozen will do.
