How to Make It
To prepare the sauce, combine the first 4 ingredients in a medium bowl, stirring with a whisk. Cover and chill 1/2 cup sauce.
To prepare the chicken, combine remaining 1 cup sauce, bell peppers, and chicken in a large bowl, and toss to coat. Cover chicken mixture, and refrigerate for 4 hours or overnight.
Preheat oven to 400°.
Remove chicken from bowl, and discard the sauce. Loosen the skin from the breast halves and leg quarters by inserting fingers, gently pushing between the skin and meat. Insert 2 lemon slices under loosened skin of each chicken piece. Place the chicken pieces, loosened skin sides up, on a broiler pan coated with cooking spray. Spread the bell peppers on broiler pan around chicken. Bake at 400° for 50 minutes or until the chicken is done. Remove the skin from the chicken. Arrange chicken and bell peppers on a platter, and keep warm.
Place 1/2 cup chilled sauce in a small saucepan, and cook over medium heat 3 minutes or until warm. Pour warm sauce over the baked chicken and bell peppers.
