Sli Red Onions N Agave Nectar & Balsamic Vinegar

Rose Mary Mogan


This is another Father's Day side dish that I served with the Baby Back Ribs, but am just getting around to posting.

They went so fast, I hardly had enough to take a display picture to show you what they looked like.

My husband loves these, & I have made them before using honey, but switched it up a bit with the Agave Nectar.

We both enjoy this side dish & he suggested I make them for burgers next time. It is different, but tasty from the butter ,balsamic & Agave, I think you may be surprised. I made them before with Prime Rib & they were fantastic, just as they were on Sunday.
