Waste not, want not. What to do with pineapple skins

Tomorrow is Easter Sunday and today we are getting things ready for our Easter dinners.   One of those things we do today is open are pineapples.
It has always bothered me how much waste there is to a pineapple. Thinking about I was trying to come up with the way to have left waste. Then it occurred to me there was a simple solution. So this morning I open the pineapple and when I was done cutting a pineapple I took the outside shell of the pineapple that remained and is usually thrown out and instead first scraped the remaining pineapple that was against the shell and got about four tablespoons of what was now like crushed pineapple and juice. Perfect amount to make a salad dressing. I combined the four tablespoons a pineapple and added 1 tablespoon of white vinegar and 1 tablespoon of olive oil and to this I added a tablespoon of mustard, salt and pepper. Give it a taste and if it is too tart for your taste add about a half teaspoon of sugar. Don't add any more because you don't want to lose the citrus taste.
During the week I will use the leftover pineapple and ham and add it to a toss salad along with orange slices and trail mix and top it with the dressing and homemade croutons.
