Quick and easy, sugarless strawberry jam

I grew up with regular strawberry freezer jam, you know, the kind with loads of sugar in it. It was delicious, but when I tasted strawberry jam sweetened with dried pineapple I knew that I had come across a very good alternative for my kids.It is very simple to make, all you do is put dried pineapple bits into a bowl and then cover with fresh strawberries. I like to mash them slightly to get the juice flowing a bit so that the pineapple softens quickly. Then just let the bowl sit in the fridge overnight.The next day just run it through the food processor then pour into small containers to freeze. I like to use small containers since it only keeps in the fridge for about a week. The resulting jam is very flavourful, not as sweet as jam made with sugar but nice, I think, because you can actually taste the fruit. Thought I would include a picture of what E looks like when he comes home from picking - the front of his shorts is just as colourful.
If you want a proper recipe I know that they used to have it at Springfield Bulk store right by the dried pineapple bin. :-)
