A healthy grilled chicken and avocado sandwich is one of my favorite lunchtime meals. It’s easy to make and full of flavor. It’s perfect as a meal prep option, too!

Creamy avocado, melted mozzarella, fresh spinach and sliced garden tomatoes perfectly complement the grilled chicken breast in this delicious panini. To save time, you could substitute rotisserie chicken breast or off-the-bone chicken breast from the deli counter. To add a little extra kick, arugula or baby power greens would be a nice alternative to the baby spinach.
If you have one, a panini press is the best tool for preparing this recipe. However, a grill pan (or even a large skillet) can also be used. Use a clean heavy cast iron skillet or a spatula to press down on the roll while toasting for best results.
If you like meal prepping, this sandwich is a perfect option! It keeps well in your storage containers and is great cold, too. My tasty Grilled Chicken Panini with Brie is also another version to try! Pair the panini with French fries, sweet potato fries, or a cup of soup.
