Using a knife, make a deep, 3”-wide cut into thickest part of each breast, to form a pocket. Season chicken with salt and pepper. Put garlic on a cutting board and pile chopped herbs on top of garlic; chop together. Smear each prosciutto slice with garlic mixture and goat cheese. Fold prosciutto into a packet and stuff into breasts; tie breasts crosswise with kitchen twine. Heat oven to 475°. Heat oil in a 12” ovenproof skillet over medium-high heat. Add chicken breasts, skin side down and brown, 6–8 minutes. Transfer skillet to oven and roast for 18 minutes. Flip breasts and cook until skin crisps, about 5 minutes. Transfer breasts to 4 plates; remove and discard twine. Squeeze lemon over chicken and serve with Alexia Roasted Red Potatoes and Baby Portabella Mushrooms.
