Preheat oven to 375° F.
In a large skillet heat 2 tablespoons of olive oil over medium heat. Add onions and peppers and sauté until softened, about 5 minutes. Add garlic and cilantro and stir until fragrant, about one minute.
Add chicken, along with water, chicken bouillon, tomato paste, onion powder, garlic powder and salt. Bring liquid to a simmer, stirring often. Allow to cook until liquid has evaporated, but mixture is not dry, about 5-8 minutes.
Cut the pie crust in half – right down the center. Separate the filling into 4 equal amounts. Working with one prepared dough at a time add one equal part of the filling onto one side of the dough.
Wet a pastry brush with egg wash (1 beaten egg plus 1 tablespoon water) and dampen the inside ¼ inch edge of the filled dough. Fold the dough in half. Using a fork, firmly press the edges together. Repeat this process with remaining dough and filling and arrange on a parchment lined baking sheet.
Brush each empanada with egg wash. Bake for 35 min or until golden brown.
