  • Top a pizza with caramelized onions.
  • They make a great addition to a side dish.
  • Just steam or roast some veggies like broccoli, asparagus or carrots and throw in some foil roasted caramelized onions for a super simple but yummy side.
  • Add some green or red peppers and you have the makings for fajitas.

    WOW I never thought of wrapping an onion in foil and baking–it makes a lot of sense. I do love onions but klutzy me generally burns them on top of the stove.
