4 cups sliced onions (4 onions)
4 tsp honey mustard -- you can buy premade. I made my own. Mixed equal parts honey & musatrd.
8 slices whole wheat bread
4 sliced cheese (I used provolone, could use any type you like!)
Heat oil in skillet, add onions, cook over low heat 30 minutes, stirring occasionally - until onions reduce and caramelize.
Preheat panini grill or sandwich maker (I used grill pan & panini press - can also use flat pan & heavy pan on top). Spread 1 tsp of the honey ustard on each of 4 bread slices. Top evenly with carmelized onions & 1 slice of cheeese. Top with remaining bread pieces.
Place sandwiches on grill, press for 4 minutes until cheese is melted. Flip halfway through if using a pan & press/weight. Serve!
These were DELICIOUS!!! We had them with a salad - spring mix greens, cucumbers, tomatoes, fat free feta & homemade balsamic! (dressing recipe below) We will be having these again! YUM!
