French Onion Chicken Sandwich

Cooks Note: I love this sandwich! I am a big onion lover, so I knew this one would be good, but I didn't expect it to be this good. I did change a couple things, I used regular hamburger buns, but I buttered them and toasted them in the same pan I cooked the onions in, also, I made a garlic aioli to give the sandwich a little moisture. For the aioli I just took regular Hellman's light mayo and I added a little basil and some garlic powder. You can make it as garlicky as you want! This is a definite favorite in my house. Enjoy!

Ingredients: 

• 1 T extra virgin olive oil
• 1 large white onion, thinly sliced

• Mayo

Directions:

1. In large skillet, add oil over medium heat. Add onion slices and sugar, cooking for 25 min or until onions are caramelized, stirring frequently. This step can be done in advance and the onions reheated prior to serving. 
2. Season chicken with salt and pepper. Either grill or saute chicken breasts till browned on the outside and no longer pink in the middle. 
3. Place cheese slices over chicken 1 minute prior to removing from heat.

5. Butter and toast hamburger buns if desired for extra flavor
