These Portobello Mushroom Quesadillas with Caramelized Onions were created with my husband in mind as a healthier alternative to his preferred steak and cheese quesadilla. The mushrooms have the similar texture, taste and feel of meat but are much easier to digest. They also help combat cancer and inflammation, and are full of protein, beneficial vitamins and minerals.
I added some caramelized onions for added flavor; they are also an antioxidant! However, I didn't stop there. I threw in some arugula, a power food that added some peppery zest! Add your favorite shredded cheese and you will have a tasty treat!
I caramelize the onions the day before, then prepare, arrange and pre-cook the quesadillas before the guests arrive. These Portobello Mushroom Quesadillas are great as an appetizer or a main meal and are easy to assemble ahead of time.
It's easy to then reheat them. Then just cut them and lay them out on a platter with the chopped arugula sprinkled over the top. Your guests will be impressed!
Great as an appetizer or a main course.

Notes
Gr8 Do Ahead Tip:
- The onions can be caramelized the day before and refrigerated, covered.
