You will start by making the caprese salad topping first. Add 1/2 cup chopped basil, 1/3 cup finely chopped red onion, 1/3 cup chopped cherry tomatoes, 2 cloves minced garlic & 1/4 tsp salt into a resealable container. Squeeze the lemon juice over it. Mix well & then let it sit to marinade in fridge while chicken is cooking
Next place your 3 butterflied chicken breasts in a baking dish, sprinkle generously with salt & pepper on each side
Then in a bowl mix together HGHF pesto & greek yogurt. Then Take out 2/3 of it into a separate bowl so you can baste your chicken with that Greek Yogurt pesto mixture. You don't want to continue to put the baster that was touching the raw chicken back into some that you might want to use for wraps. So keeping 1/3 out for pasta or wraps is nice to do.
Take the 2/3 of the mixture and with a basting brush, baste both sides of the chicken breasts. Let marinade for 30 minutes.
Spray your grill with olive oil BEFORE turning it on, to prevent chicken from sticking. Then turn to medium heat.
Once grill is preheated, add your butterflied chicken breasts to the grill. Since they are butterflied they will be thinner than regular chicken breasts. So grill about 4 minutes PER side until internal temperature reacts 165F.
The LAST 2 minutes, add your sprinkled mozzarella on each butterflied chicken breast & close lid.
Once internal temp is at 165, you will take your chicken off the grill, let it rest for 5 minutes before cutting in & top with your caprese salad mixture! Enjoy!
