Let's start by giving those chicken breasts some love. Butterfly them and give them a little TLC with a flattening session. We want them to be thin and fabulous.

Shake things up by mixing paprika, Italian seasoning, salt, and pepper. Sprinkle that mix all over the chicken, making sure it's partying on both sides.

Heat up a pan, add a splash of avocado oil, and let's get those chicken breasts sizzling. Cook them until they're golden brown and doing a happy dance.

Time for the ciabatta rolls to join the party. Pop them in the pan and press them down with your magical fingers until they're golden and crispy. Then, give them a well-deserved break on the sidelines.

Now comes the fun part – assembling! Lay those ciabatta rolls on a baking sheet and start spreading the mayo love on the bottom halves.

Arugula, come on down! Sprinkle some of that vibrant goodness onto the mayo-covered rolls.

The chicken takes the stage next. Place those golden beauties on the arugula, and let's make them feel at home.

Cherry tomatoes, you're up! Give them a happy place on the chicken, cut side up, so they can share their juicy vibes.

Say cheese! Load up the fresh mozzarella slices onto the tomatoes. It's like building a flavor skyscraper.

Pesto, you saucy thing. Slather that pesto goodness on the top halves of the ciabatta rolls, and don't hold back!

Drumroll, please. Set your oven to broil mode, and let's get those sandwiches a little toasty. Only the bottom halves get the broiler spotlight – just until the mozzarella starts melting into a gooey masterpiece.

Remove the bottom halves from the oven and give them a round of applause. The top halves can sit this one out – no broiler action for them.

Carefully place the top halves over the cheesy, melty goodness and press gently.

Get ready to taste the magic! Your Pesto Mozzarella Chicken Sandwiches are ready to steal the show.
