Preheat oven to 425°.
Cook beef in a small nonstick skillet over medium-high heat until browned, stirring to crumble. Drain well, and return beef to pan. Add onion, bell pepper, and garlic, and sauté 5 minutes or until tender. Remove from heat, and stir in raisins and next 5 ingredients (raisins through salt).
Divide the pizza crust dough into 18 portions; cover dough, and let rest 5 minutes. Shape each dough portion into a ball, and roll each portion into a 3-inch circle on a lightly floured surface. Spoon 2 level teaspoons of beef mixture onto half of each dough circle. Moisten edges of dough with water. Fold dough over beef filling, and press edges together to seal. Place empanaditas on a large baking sheet coated with cooking spray. Lightly coat tops of empanaditas with cooking spray. Bake at 425° for 10 minutes or until lightly browned.
