Prepare your jars - set aside
Pulse your pineapple & red pepper pieces in food processor until rough cut into semi- small pieces
Transfer to medium saucepan & add vinegar & sugar
Bring to a rolling boil - stirring the entire time
Remove from heat & stir in pectin until completely dissolved
If you want brighter color- this is the time to stir in your food color (I used yellow)
Pour into your sterilized jars & either seal in water bath for 15 minutes or store in refrigerator for up to 2 weeks or in freezer for up to 6 months.
