*Guava paste is available in Mexican & Spanish groceries. If you cannot find it, you can substitute the same amount of jellied cranberry sauce. Place one chicken breast half between 2 pieces of plastic wrap or waxed paper. Working from center, gently pound chicken with rolling pin or flat side of meat mallet until about 1/4" thick. Repeat with remaining chicken breasts. In small bowl, combine salt, oregano, pepper and garlic; mix well. Sprinkle evenly over chicken breasts. Form guava paste into four 2 x 1/2 x 1/2" strips and place one on each ham slice. Spoon about a tablespoonful of cilantro over each strip of guava paste. Fold ham around guava and cilantro to form a foll. Place one roll on narrow end of each chicken half; roll up, jelly-roll fashion. Secure with toothpicks. Heat 1 T oil in skillet over medium heat; add chicken rolls, seam side down. Cook covered for 6 minutes or until no longer pink, turning once halfway through cooking. Remove toothpicks. Place chicken on paper towels; pat dry. Heat oven to 375 degrees. Separate dough into 4 rectangles; firmly press perforations to seal. Place one chicken roll on each rectangle. Fold dough over chicken; press edges to seal. Place, seam side down, on ungreased cookie sheet. Cut slits in tops to allow steam to escape. Bake for 13 to 18 minutes or until golden brown. Meanwhile, in small saucepan over low heat, combine all sauce ingredients; cook and stir until guava paste melts. Simmer until sauce thickens. Place chicken bundles on serving plates; top with sauce. Garnish with additional cilantro, if desired. Serve immediately. (2/3 cup sauce)
