These Giardiniera Chicken Melts take classic grilled chicken to the next level and I cannot get enough of them! Saucy, cheesy, tangy, what more could you want?

If you are not familiar, giardiniera is an Italian relish that consists of pickled vegetables in vinegar or oil. It can pack a punch if you get the hot which I love! But mild or hot, the pickled flavor adds a delicious tang to this dish.

This recipe starts by simply marinating your butterflied chicken breasts and prepping your veggies. You’ll then grill the chicken and veggies. Once the chicken is almost complete, you’ll top each chicken breast with marinara, mozzarella, and the giardiniera and let cook until the cheese is nice and melted. Serve alongside the veggies and your #DDGrillWeek 2024 dinner will be ready to go!

Ingredients:
- Garlic
- Fresh Oregano
- Fresh Parsley
- Extra Virgin Olive Oil
- Salt
- Freshly Ground Black Pepper
- Lemon Zest and Juice
- Red Wine Vinegar
- Boneless, Skinless Chicken Breasts
- Mini Peppers
- Zucchinis
- Marinara
- Shredded Mozzarella Cheese
- Mild or Hot Giardiniera
Recipe Step-by-Step:
Step One: Make the Chicken Marinade
In a large bowl, whisk together the garlic, oregano, parsley, olive oil, salt, pepper, lemon zest, lemon juice, and red wine vinegar until well combined. Set aside.

Step Two: Prep the Chicken
On a large cutting board, slice the chicken breasts open lengthwise, without slicing all of the way through the breasts, like a book. Cover with saran wrap and using a meat mallet, pound the chicken so that it is an even ¼-inch thickness. Transfer the butterflied chicken to the marinade and toss to coat. Set aside at room temperature to marinade for at least 30 minutes, or in the fridge for up to 4 hours.
Step Three: Prep the Veggies
Meanwhile, place the mini bell peppers and sliced zucchini on a large sheet pan and drizzle with the olive oil. Season with salt and pepper. Set aside.
Step Four: Prep the Grill
Heat the grill over medium-high heat (350-400℉) and oil the grill grates. To do this, dip a wadded paper towel in a little avocado oil and, using tongs, wipe the oil evenly over the grate. Be careful not to use too much oil, because that’s a sure-fire way to start a good flare-up—a little goes a long way here.
Step Five: Start the Chicken
Add the chicken to one half of the grill and cook for 4 minutes per side, until the pieces turn golden and grill marks appear. The lid should be closed throughout the cooking process.
Step Six: Grill the Veggies
To the other half of the grill, add the mini bell peppers and zucchini, in a single layer. Grill for about 6 minutes total, flipping halfway through, until grill marks appear and the zucchini is tender and the bell peppers soften. Transfer to a serving platter and set aside.
Step Seven: Finish the Chicken
Reduce the heat to medium-low and divide the marinara on top of each of the chicken breasts. Next, top with the mozzarella, then the giardiniera. Close the lid and let cook until the cheese is nice and melty, 3 to 4 more minutes.
Step Eight: Serve and Enjoy!
Transfer the cooked chicken to a serving platter and garnish with fresh parsley.

I rarely ever duplicate a recipe in the same month. I can’t help it with this one. I am making it for the third time today.
Haha incredible! Thanks for the review!
Holy yum!! I love DD grill week and this recipe did not disappoint at all. Super simple and packed full of flavor. My 5 year old ate it too, which is a huge bonus!
Glad it was a hit!
We loved these! This was seriously so simple & the flavors of the giardinier, marinara & mozzarella together is AMAZING. We had one person that isn’t a giardinier fan & they still loved the meal without it (kinda like a grilled chicken parm). Definitely will be making this again!
