Drain pineapple well; pat dry with paper towels.
Stir together pineapple and next 4 ingredients in a small saucepan over medium heat, and bring to a boil. Reduce heat to low, and simmer, stirring often, 5 minutes or until thickened. Remove from heat, and stir in jalapeño and green onions. Cover and chill until ready to serve.
I serve this over cream cheese & add pumpkin pie spice to it. Yummy!
