Preheat oven to 400 F. In a plastic bag, combine potatoes, olive oil, seasoned salt, pepper, garlic & lemon zest; toss well. Place on a foil lined large baking sheet & roast for 10 minutes.
Chicken Breast/Stuffing
Place walnuts, 1 cup fresh basil & garlic in food processor; slowly add 1 Tbsp olive oil until mixture becomes paste-like. Next add brie, cream cheese & egg to the food processor & pulse until mixed well. Season with salt, pepper & pepper flakes.
Place chicken breasts between 2 sheets of plastic wrap & carefully flatten with a meat mallet. Divide stuffing between the 4 breasts. Roll up or fold over, enclosing filling well. In a small bowl, combine apricot preserves, balsamic vinegar & remaining Tbsp olive oil.
Remove potatoes from oven & slide them around a bit to make room for the chicken. Place the chicken on the pan; brush apricot mixture all over breasts. Place the pan back in the oven & roast for 30-40 minutes or until the chicken is cooked through & potatoes are golden. Garnish with fresh basil if preferred.
