1Heat oven to 400°F. In large bowl, mix apples and lemon juice. In small bowl, mix 1/2 cup sugar, the tapioca, cinnamon, salt and nutmeg. Add to apples; stir gently. Let stand 15 minutes. Place 1 pie crust in ungreased 9-inch glass pie plate. Pour apple mixture into pastry-lined pie plate.
2In small bowl, mix oats, flour and 3 tablespoons sugar. Cut in butter until crumbly. Sprinkle over apples. Cut second crust into wedges; arrange wedges in an alternate pattern across the mixture.
3Bake 45 minutes. Meanwhile, in 1-quart saucepan, heat caramels and milk over low heat until caramels are melted. Stir until smooth; add pecans. Drizzle over pie. Bake 8 to 10 minutes longer or until crust is golden brown and filling is bubbly. Cool completely on cooling rack, about 2 hours.
