1Heat oven to 375°F. Spray 12 regular-size muffin cups with cooking spray.
2In 10-inch nonstick skillet, heat oil over medium-high heat. Cook chicken in oil 5 to 7 minutes, stirring occasionally, until chicken is no longer pink in center. Add onion; cook 2 to 3 minutes. Add green onions, cilantro, red curry paste and lime juice, stirring occasionally, until mixture is heated through. Cool 5 minutes; stir in cheese.
3In medium bowl, stir baking mixture ingredients with whisk or fork until blended. Spoon 1 scant tablespoon baking mixture into each muffin cup. Top with about 1/4 cup Thai chicken mixture. Spoon 1 tablespoon baking mixture onto Thai chicken mixture in each muffin cup.
4Bake 30 to 35 minutes or until toothpick inserted in center comes out clean and tops of pies are golden brown. Ten minutes into baking, carefully open oven and sprinkle 1/2 tablespoon peanuts on top of each muffin. Close oven door and finish baking. Cool 5 minutes. With thin knife, loosen sides of pies from pan; remove from pan and place top sides up on cooling rack. Cool 10 minutes longer; serve with sliced green onions.
